newtype VkIndexType Source #

VkIndexType - Type of index buffer indices

Parameters

commandBuffer is the command buffer that the pipeline will be bound to.

pipelineBindPoint is a VkPipelineBindPoint value specifying whether to bind to the compute or graphics bind point. Binding one does not disturb the other.
pipeline is the pipeline to be bound.

Description

Once bound, a pipeline binding affects subsequent graphics or compute commands in the command buffer until a different pipeline is bound to the bind point. The pipeline bound to VK_PIPELINE_BIND_POINT_COMPUTE controls the behavior of vkCmdDispatch and vkCmdDispatchIndirect. The pipeline bound to VK_PIPELINE_BIND_POINT_GRAPHICS controls the behavior of all drawing commands. No other commands are affected by the pipeline state.

Valid Usage

If pipelineBindPoint is VK_PIPELINE_BIND_POINT_COMPUTE, the VkCommandPool that commandBuffer was allocated from must support compute operations

If pipelineBindPoint is VK_PIPELINE_BIND_POINT_GRAPHICS, the VkCommandPool that commandBuffer was allocated from must support graphics operations
If pipelineBindPoint is VK_PIPELINE_BIND_POINT_COMPUTE, pipeline must be a compute pipeline
If pipelineBindPoint is VK_PIPELINE_BIND_POINT_GRAPHICS, pipeline must be a graphics pipeline
If the variable multisample rate feature is not supported, pipeline is a graphics pipeline, the current subpass has no attachments, and this is not the first call to this function with a graphics pipeline after transitioning to the current subpass, then the sample count specified by this pipeline must match that set in the previous pipeline
If VkPhysicalDeviceSampleLocationsPropertiesEXT::variableSampleLocations is VK_FALSE, and pipeline is a graphics pipeline created with a VkPipelineSampleLocationsStateCreateInfoEXT structure having its sampleLocationsEnable member set to VK_TRUE but without VK_DYNAMIC_STATE_SAMPLE_LOCATIONS_EXT enabled then the current render pass instance must have been begun by specifying a VkRenderPassSampleLocationsBeginInfoEXT structure whose pPostSubpassSampleLocations member contains an element with a subpassIndex matching the current subpass index and the sampleLocationsInfo member of that element must match the sampleLocationsInfo specified in VkPipelineSampleLocationsStateCreateInfoEXT when the pipeline was created

Valid Usage (Implicit)

commandBuffer must be a valid VkCommandBuffer handle

pipelineBindPoint must be a valid VkPipelineBindPoint value
pipeline must be a valid VkPipeline handle
commandBuffer must be in the recording state
The VkCommandPool that commandBuffer was allocated from must support graphics, or compute operations
Both of commandBuffer, and pipeline must have been created, allocated, or retrieved from the same VkDevice

Parameters

commandBuffer is the command buffer into which the command will be recorded.

depthBiasConstantFactor is a scalar factor controlling the constant depth value added to each fragment.
depthBiasClamp is the maximum (or minimum) depth bias of a fragment.
depthBiasSlopeFactor is a scalar factor applied to a fragment’s slope in depth bias calculations.

Description

If depthBiasEnable is VK_FALSE, no depth bias is applied and the fragment’s depth values are unchanged.

depthBiasSlopeFactor scales the maximum depth slope of the polygon, and depthBiasConstantFactor scales an implementation-dependent constant that relates to the usable resolution of the depth buffer. The resulting values are summed to produce the depth bias value which is then clamped to a minimum or maximum value specified by depthBiasClamp. depthBiasSlopeFactor, depthBiasConstantFactor, and depthBiasClamp can each be positive, negative, or zero.

The maximum depth slope m of a triangle is

\[m = \sqrt{ \left({{\partial z_f} \over {\partial x_f}}\right)^2 + \left({{\partial z_f} \over {\partial y_f}}\right)^2}\]

where (xf, yf, zf) is a point on the triangle. m may be approximated as

\[m = \max\left( \left| { {\partial z_f} \over {\partial x_f} } \right|, \left| { {\partial z_f} \over {\partial y_f} } \right| \right).\]

The minimum resolvable difference r is an implementation-dependent parameter that depends on the depth buffer representation. It is the smallest difference in framebuffer coordinate z values that is guaranteed to remain distinct throughout polygon rasterization and in the depth buffer. All pairs of fragments generated by the rasterization of two polygons with otherwise identical vertices, but zf values that differ by $r$, will have distinct depth values.

For fixed-point depth buffer representations, r is constant throughout the range of the entire depth buffer. For floating-point depth buffers, there is no single minimum resolvable difference. In this case, the minimum resolvable difference for a given polygon is dependent on the maximum exponent, e, in the range of z values spanned by the primitive. If n is the number of bits in the floating-point mantissa, the minimum resolvable difference, r, for the given primitive is defined as

r = 2e-n

If a triangle is rasterized using the VK_POLYGON_MODE_FILL_RECTANGLE_NV polygon mode, then this minimum resolvable difference may not be resolvable for samples outside of the triangle, where the depth is extrapolated.

If no depth buffer is present, r is undefined.

The bias value o for a polygon is

\[o = \begin{cases} m \times depthBiasSlopeFactor + r \times depthBiasConstantFactor & depthBiasClamp = 0\ or\ NaN \\ \min(m \times depthBiasSlopeFactor + r \times depthBiasConstantFactor, depthBiasClamp) & depthBiasClamp > 0 \\ \max(m \times depthBiasSlopeFactor + r \times depthBiasConstantFactor, depthBiasClamp) & depthBiasClamp < 0 \\ \end{cases}\]

m is computed as described above. If the depth buffer uses a fixed-point representation, m is a function of depth values in the range [0,1], and o is applied to depth values in the same range.

For fixed-point depth buffers, fragment depth values are always limited to the range [0,1] by clamping after depth bias addition is performed. Unless the {html_spec_relative}#VK_EXT_depth_range_unrestricted extension is enabled, fragment depth values are clamped even when the depth buffer uses a floating-point representation.

Parameters

commandBuffer is the command buffer that the descriptor sets will be bound to.

pipelineBindPoint is a VkPipelineBindPoint indicating whether the descriptors will be used by graphics pipelines or compute pipelines. There is a separate set of bind points for each of graphics and compute, so binding one does not disturb the other.
layout is a VkPipelineLayout object used to program the bindings.
firstSet is the set number of the first descriptor set to be bound.
descriptorSetCount is the number of elements in the pDescriptorSets array.
pDescriptorSets is an array of handles to VkDescriptorSet objects describing the descriptor sets to write to.
dynamicOffsetCount is the number of dynamic offsets in the pDynamicOffsets array.
pDynamicOffsets is a pointer to an array of uint32_t values specifying dynamic offsets.

Description

vkCmdBindDescriptorSets causes the sets numbered [firstSet.. firstSet+descriptorSetCount-1] to use the bindings stored in pDescriptorSets[0..descriptorSetCount-1] for subsequent rendering commands (either compute or graphics, according to the pipelineBindPoint). Any bindings that were previously applied via these sets are no longer valid.

Once bound, a descriptor set affects rendering of subsequent graphics or compute commands in the command buffer until a different set is bound to the same set number, or else until the set is disturbed as described in Pipeline Layout Compatibility.

A compatible descriptor set must be bound for all set numbers that any shaders in a pipeline access, at the time that a draw or dispatch command is recorded to execute using that pipeline. However, if none of the shaders in a pipeline statically use any bindings with a particular set number, then no descriptor set need be bound for that set number, even if the pipeline layout includes a non-trivial descriptor set layout for that set number.

If any of the sets being bound include dynamic uniform or storage buffers, then pDynamicOffsets includes one element for each array element in each dynamic descriptor type binding in each set. Values are taken from pDynamicOffsets in an order such that all entries for set N come before set N+1; within a set, entries are ordered by the binding numbers in the descriptor set layouts; and within a binding array, elements are in order. dynamicOffsetCount must equal the total number of dynamic descriptors in the sets being bound.

The effective offset used for dynamic uniform and storage buffer bindings is the sum of the relative offset taken from pDynamicOffsets, and the base address of the buffer plus base offset in the descriptor set. The length of the dynamic uniform and storage buffer bindings is the buffer range as specified in the descriptor set.

Each of the pDescriptorSets must be compatible with the pipeline layout specified by layout. The layout used to program the bindings must also be compatible with the pipeline used in subsequent graphics or compute commands, as defined in the Pipeline Layout Compatibility section.

The descriptor set contents bound by a call to vkCmdBindDescriptorSets may be consumed at the following times:

For descriptor bindings created with the VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT_EXT bit set, the contents may be consumed when the command buffer is submitted to a queue, or during shader execution of the resulting draws and dispatches, or any time in between. Otherwise,
during host execution of the command, or during shader execution of the resulting draws and dispatches, or any time in between.

Thus, the contents of a descriptor set binding must not be altered (overwritten by an update command, or freed) between the first point in time that it may be consumed, and and when the command completes executing on the queue.

The contents of pDynamicOffsets are consumed immediately during execution of vkCmdBindDescriptorSets. Once all pending uses have completed, it is legal to update and reuse a descriptor set.

Valid Usage

Each element of pDescriptorSets must have been allocated with a VkDescriptorSetLayout that matches (is the same as, or identically defined as) the VkDescriptorSetLayout at set n in layout, where n is the sum of firstSet and the index into pDescriptorSets

dynamicOffsetCount must be equal to the total number of dynamic descriptors in pDescriptorSets
The sum of firstSet and descriptorSetCount must be less than or equal to VkPipelineLayoutCreateInfo::setLayoutCount provided when layout was created
pipelineBindPoint must be supported by the commandBuffer’s parent VkCommandPool’s queue family
Each element of pDynamicOffsets must satisfy the required alignment for the corresponding descriptor binding’s descriptor type

commandBuffer must be a valid VkCommandBuffer handle

pipelineBindPoint must be a valid VkPipelineBindPoint value
layout must be a valid VkPipelineLayout handle
pDescriptorSets must be a valid pointer to an array of descriptorSetCount valid VkDescriptorSet handles
If dynamicOffsetCount is not 0, pDynamicOffsets must be a valid pointer to an array of dynamicOffsetCount uint32_t values
commandBuffer must be in the recording state
The VkCommandPool that commandBuffer was allocated from must support graphics, or compute operations
descriptorSetCount must be greater than 0
Each of commandBuffer, layout, and the elements of pDescriptorSets must have been created, allocated, or retrieved from the same VkDevice

Parameters

commandBuffer is the command buffer into which the command is recorded.

indexCount is the number of vertices to draw.
instanceCount is the number of instances to draw.
firstIndex is the base index within the index buffer.
vertexOffset is the value added to the vertex index before indexing into the vertex buffer.
firstInstance is the instance ID of the first instance to draw.

Description

When the command is executed, primitives are assembled using the current primitive topology and indexCount vertices whose indices are retrieved from the index buffer. The index buffer is treated as an array of tightly packed unsigned integers of size defined by the vkCmdBindIndexBuffer::indexType parameter with which the buffer was bound.

The first vertex index is at an offset of firstIndex * indexSize + offset within the bound index buffer, where offset is the offset specified by vkCmdBindIndexBuffer and indexSize is the byte size of the type specified by indexType. Subsequent index values are retrieved from consecutive locations in the index buffer. Indices are first compared to the primitive restart value, then zero extended to 32 bits (if the indexType is VK_INDEX_TYPE_UINT16) and have vertexOffset added to them, before being supplied as the vertexIndex value.

The primitives are drawn instanceCount times with instanceIndex starting with firstInstance and increasing sequentially for each instance. The assembled primitives execute the bound graphics pipeline.

Parameters

commandBuffer is the command buffer into which the command will be recorded.

srcImage is the source image.
srcImageLayout is the current layout of the source image subresource.
dstImage is the destination image.
dstImageLayout is the current layout of the destination image subresource.
regionCount is the number of regions to copy.
pRegions is a pointer to an array of VkImageCopy structures specifying the regions to copy.

Description

Each region in pRegions is copied from the source image to the same region of the destination image. srcImage and dstImage can be the same image or alias the same memory.

The formats of srcImage and dstImage must be compatible. Formats are considered compatible if their element size is the same between both formats. For example, VK_FORMAT_R8G8B8A8_UNORM is compatible with VK_FORMAT_R32_UINT because both texels are 4 bytes in size. Depth/stencil formats must match exactly.

If the format of srcImage or dstImage is a multi-planar image format, regions of each plane to be copied must be specified separately using the srcSubresource and dstSubresource members of the VkImageCopy structure. In this case, the aspectMask of the srcSubresource or dstSubresource that refers to the multi-planar image must be VK_IMAGE_ASPECT_PLANE_0_BIT, VK_IMAGE_ASPECT_PLANE_1_BIT, or VK_IMAGE_ASPECT_PLANE_2_BIT. For the purposes of vkCmdCopyImage, each plane of a multi-planar image is treated as having the format listed in {html_spec_relative}#features-formats-compatible-planes for the plane identified by the aspectMask of the corresponding subresource. This applies both to VkFormat and to coordinates used in the copy, which correspond to texels in the plane rather than how these texels map to coordinates in the image as a whole.

Note

For example, the VK_IMAGE_ASPECT_PLANE_1_BIT plane of a VK_FORMAT_G8_B8R8_2PLANE_420_UNORM image is compatible with an image of format VK_FORMAT_R8G8_UNORM and (less usefully) with the VK_IMAGE_ASPECT_PLANE_0_BIT plane of an image of format VK_FORMAT_G10X6_B10X6_R10X6_3PLANE_420_UNORM_3PACK16, as each texel is 2 bytes in size.

vkCmdCopyImage allows copying between size-compatible compressed and uncompressed internal formats. Formats are size-compatible if the element size of the uncompressed format is equal to the element size (compressed texel block size) of the compressed format. Such a copy does not perform on-the-fly compression or decompression. When copying from an uncompressed format to a compressed format, each texel of uncompressed data of the source image is copied as a raw value to the corresponding compressed texel block of the destination image. When copying from a compressed format to an uncompressed format, each compressed texel block of the source image is copied as a raw value to the corresponding texel of uncompressed data in the destination image. Thus, for example, it is legal to copy between a 128-bit uncompressed format and a compressed format which has a 128-bit sized compressed texel block representing 4×4 texels (using 8 bits per texel), or between a 64-bit uncompressed format and a compressed format which has a 64-bit sized compressed texel block representing 4×4 texels (using 4 bits per texel).

When copying between compressed and uncompressed formats the extent members represent the texel dimensions of the source image and not the destination. When copying from a compressed image to an uncompressed image the image texel dimensions written to the uncompressed image will be source extent divided by the compressed texel block dimensions. When copying from an uncompressed image to a compressed image the image texel dimensions written to the compressed image will be the source extent multiplied by the compressed texel block dimensions. In both cases the number of bytes read and the number of bytes written will be identical.

Copying to or from block-compressed images is typically done in multiples of the compressed texel block size. For this reason the extent must be a multiple of the compressed texel block dimension. There is one exception to this rule which is required to handle compressed images created with dimensions that are not a multiple of the compressed texel block dimensions: if the srcImage is compressed, then:

If extent.width is not a multiple of the compressed texel block width, then (extent.width + srcOffset.x) must equal the image subresource width.
If extent.height is not a multiple of the compressed texel block height, then (extent.height + srcOffset.y) must equal the image subresource height.
If extent.depth is not a multiple of the compressed texel block depth, then (extent.depth + srcOffset.z) must equal the image subresource depth.

Similarly, if the dstImage is compressed, then:

If extent.width is not a multiple of the compressed texel block width, then (extent.width + dstOffset.x) must equal the image subresource width.
If extent.height is not a multiple of the compressed texel block height, then (extent.height + dstOffset.y) must equal the image subresource height.
If extent.depth is not a multiple of the compressed texel block depth, then (extent.depth + dstOffset.z) must equal the image subresource depth.

This allows the last compressed texel block of the image in each non-multiple dimension to be included as a source or destination of the copy.

“_422” image formats that are not multi-planar are treated as having a 2×1 compressed texel block for the purposes of these rules.

vkCmdCopyImage can be used to copy image data between multisample images, but both images must have the same number of samples.

Parameters

commandBuffer is the command buffer into which the command will be recorded.

srcImage is the source image.
srcImageLayout is the layout of the source image subresources for the blit.
dstImage is the destination image.
dstImageLayout is the layout of the destination image subresources for the blit.
regionCount is the number of regions to blit.
pRegions is a pointer to an array of VkImageBlit structures specifying the regions to blit.
filter is a VkFilter specifying the filter to apply if the blits require scaling.

Description

vkCmdBlitImage must not be used for multisampled source or destination images. Use vkCmdResolveImage for this purpose.

As the sizes of the source and destination extents can differ in any dimension, texels in the source extent are scaled and filtered to the destination extent. Scaling occurs via the following operations:

For each destination texel, the integer coordinate of that texel is converted to an unnormalized texture coordinate, using the effective inverse of the equations described in unnormalized to integer conversion:
- ubase = i + ½
- vbase = j + ½
- wbase = k + ½
These base coordinates are then offset by the first destination offset:
- uoffset = ubase - xdst0
- voffset = vbase - ydst0
- woffset = wbase - zdst0
- aoffset = a - baseArrayCountdst
The scale is determined from the source and destination regions, and applied to the offset coordinates:
- scale_u = (xsrc1 - xsrc0) / (xdst1 - xdst0)
- scale_v = (ysrc1 - ysrc0) / (ydst1 - ydst0)
- scale_w = (zsrc1 - zsrc0) / (zdst1 - zdst0)
- uscaled = uoffset * scaleu
- vscaled = voffset * scalev
- wscaled = woffset * scalew
Finally the source offset is added to the scaled coordinates, to determine the final unnormalized coordinates used to sample from srcImage:
- u = uscaled + xsrc0
- v = vscaled + ysrc0
- w = wscaled + zsrc0
- q = mipLevel
- a = aoffset + baseArrayCountsrc

These coordinates are used to sample from the source image, as described in Image Operations chapter, with the filter mode equal to that of filter, a mipmap mode of VK_SAMPLER_MIPMAP_MODE_NEAREST and an address mode of VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_EDGE. Implementations must clamp at the edge of the source image, and may additionally clamp to the edge of the source region.

Note

Due to allowable rounding errors in the generation of the source texture coordinates, it is not always possible to guarantee exactly which source texels will be sampled for a given blit. As rounding errors are implementation dependent, the exact results of a blitting operation are also implementation dependent.

Blits are done layer by layer starting with the baseArrayLayer member of srcSubresource for the source and dstSubresource for the destination. layerCount layers are blitted to the destination image.

3D textures are blitted slice by slice. Slices in the source region bounded by srcOffsets[0].z and srcOffsets[1].z are copied to slices in the destination region bounded by dstOffsets[0].z and dstOffsets[1].z. For each destination slice, a source z coordinate is linearly interpolated between srcOffsets[0].z and srcOffsets[1].z. If the filter parameter is VK_FILTER_LINEAR then the value sampled from the source image is taken by doing linear filtering using the interpolated z coordinate. If filter parameter is VK_FILTER_NEAREST then value sampled from the source image is taken from the single nearest slice (with undefined rounding mode).

The following filtering and conversion rules apply:

Integer formats can only be converted to other integer formats with the same signedness.
No format conversion is supported between depth/stencil images. The formats must match.
Format conversions on unorm, snorm, unscaled and packed float formats of the copied aspect of the image are performed by first converting the pixels to float values.
For sRGB source formats, nonlinear RGB values are converted to linear representation prior to filtering.
After filtering, the float values are first clamped and then cast to the destination image format. In case of sRGB destination format, linear RGB values are converted to nonlinear representation before writing the pixel to the image.

Signed and unsigned integers are converted by first clamping to the representable range of the destination format, then casting the value.

Parameters

commandBuffer is the command buffer into which the command will be recorded.

dstBuffer is a handle to the buffer to be updated.
dstOffset is the byte offset into the buffer to start updating, and must be a multiple of 4.
dataSize is the number of bytes to update, and must be a multiple of 4.
pData is a pointer to the source data for the buffer update, and must be at least dataSize bytes in size.

Description

dataSize must be less than or equal to 65536 bytes. For larger updates, applications can use buffer to buffer copies.

Note

Buffer updates performed with vkCmdUpdateBuffer first copy the data into command buffer memory when the command is recorded (which requires additional storage and may incur an additional allocation), and then copy the data from the command buffer into dstBuffer when the command is executed on a device.

The additional cost of this functionality compared to buffer to buffer copies means it is only recommended for very small amounts of data, and is why it is limited to only 65536 bytes.

Applications can work around this by issuing multiple vkCmdUpdateBuffer commands to different ranges of the same buffer, but it is strongly recommended that they should not.

The source data is copied from the user pointer to the command buffer when the command is called.

vkCmdUpdateBuffer is only allowed outside of a render pass. This command is treated as “transfer” operation, for the purposes of synchronization barriers. The VK_BUFFER_USAGE_TRANSFER_DST_BIT must be specified in usage of VkBufferCreateInfo in order for the buffer to be compatible with vkCmdUpdateBuffer.

Valid Usage

dstOffset must be less than the size of dstBuffer

dataSize must be less than or equal to the size of dstBuffer minus dstOffset
dstBuffer must have been created with VK_BUFFER_USAGE_TRANSFER_DST_BIT usage flag
If dstBuffer is non-sparse then it must be bound completely and contiguously to a single VkDeviceMemory object
dstOffset must be a multiple of 4
dataSize must be less than or equal to 65536
dataSize must be a multiple of 4

Valid Usage (Implicit)

commandBuffer must be a valid VkCommandBuffer handle

dstBuffer must be a valid VkBuffer handle
pData must be a valid pointer to an array of dataSize bytes

Parameters

commandBuffer is the command buffer into which the command will be recorded.

srcImage is the source image.

Parameters

commandBuffer is the command buffer into which the command is recorded.

event is the event that will be signaled.
stageMask specifies the source stage mask used to determine when the event is signaled.

Description

When vkCmdSetEvent is submitted to a queue, it defines an execution dependency on commands that were submitted before it, and defines an event signal operation which sets the event to the signaled state.

The first synchronization scope includes all commands that occur earlier in submission order. The synchronization scope is limited to operations on the pipeline stages determined by the source stage mask specified by stageMask.

The second synchronization scope includes only the event signal operation.

If event is already in the signaled state when vkCmdSetEvent is executed on the device, then vkCmdSetEvent has no effect, no event signal operation occurs, and no execution dependency is generated.

Valid Usage

stageMask must not include VK_PIPELINE_STAGE_HOST_BIT

If the geometry shaders feature is not enabled, stageMask must not contain VK_PIPELINE_STAGE_GEOMETRY_SHADER_BIT
If the tessellation shaders feature is not enabled, stageMask must not contain VK_PIPELINE_STAGE_TESSELLATION_CONTROL_SHADER_BIT or VK_PIPELINE_STAGE_TESSELLATION_EVALUATION_SHADER_BIT

Parameters

commandBuffer is the command buffer into which the command is recorded.

event is the event that will be unsignaled.
stageMask is a bitmask of VkPipelineStageFlagBits specifying the source stage mask used to determine when the event is unsignaled.

Description

When vkCmdResetEvent is submitted to a queue, it defines an execution dependency on commands that were submitted before it, and defines an event unsignal operation which resets the event to the unsignaled state.

The first synchronization scope includes all commands that occur earlier in submission order. The synchronization scope is limited to operations on the pipeline stages determined by the source stage mask specified by stageMask.

The second synchronization scope includes only the event unsignal operation.

If event is already in the unsignaled state when vkCmdResetEvent is executed on the device, then vkCmdResetEvent has no effect, no event unsignal operation occurs, and no execution dependency is generated.

Valid Usage

If the geometry shaders feature is not enabled, stageMask must not contain VK_PIPELINE_STAGE_GEOMETRY_SHADER_BIT
If the tessellation shaders feature is not enabled, stageMask must not contain VK_PIPELINE_STAGE_TESSELLATION_CONTROL_SHADER_BIT or VK_PIPELINE_STAGE_TESSELLATION_EVALUATION_SHADER_BIT

Parameters

commandBuffer is the command buffer into which the command is recorded.

eventCount is the length of the pEvents array.
pEvents is an array of event object handles to wait on.
srcStageMask is a bitmask of VkPipelineStageFlagBits specifying the source stage mask.
dstStageMask is a bitmask of VkPipelineStageFlagBits specifying the destination stage mask.
memoryBarrierCount is the length of the pMemoryBarriers array.
pMemoryBarriers is a pointer to an array of VkMemoryBarrier structures.
bufferMemoryBarrierCount is the length of the pBufferMemoryBarriers array.
pBufferMemoryBarriers is a pointer to an array of VkBufferMemoryBarrier structures.
imageMemoryBarrierCount is the length of the pImageMemoryBarriers array.
pImageMemoryBarriers is a pointer to an array of VkImageMemoryBarrier structures.

Description

When vkCmdWaitEvents is submitted to a queue, it defines a memory dependency between prior event signal operations on the same queue or the host, and subsequent commands. vkCmdWaitEvents must not be used to wait on event signal operations occuring on other queues.

The first synchronization scope only includes event signal operations that operate on members of pEvents, and the operations that happened-before the event signal operations. Event signal operations performed by vkCmdSetEvent that occur earlier in submission order are included in the first synchronization scope, if the logically latest pipeline stage in their stageMask parameter is logically earlier than or equal to the logically latest pipeline stage in srcStageMask. Event signal operations performed by vkSetEvent are only included in the first synchronization scope if VK_PIPELINE_STAGE_HOST_BIT is included in srcStageMask.

The second synchronization scope includes all commands that occur later in submission order. The second synchronization scope is limited to operations on the pipeline stages determined by the destination stage mask specified by dstStageMask.

The first access scope is limited to access in the pipeline stages determined by the source stage mask specified by srcStageMask. Within that, the first access scope only includes the first access scopes defined by elements of the pMemoryBarriers, pBufferMemoryBarriers and pImageMemoryBarriers arrays, which each define a set of memory barriers. If no memory barriers are specified, then the first access scope includes no accesses.

The second access scope is limited to access in the pipeline stages determined by the destination stage mask specified by dstStageMask. Within that, the second access scope only includes the second access scopes defined by elements of the pMemoryBarriers, pBufferMemoryBarriers and pImageMemoryBarriers arrays, which each define a set of memory barriers. If no memory barriers are specified, then the second access scope includes no accesses.

Note

vkCmdWaitEvents is used with vkCmdSetEvent to define a memory dependency between two sets of action commands, roughly in the same way as pipeline barriers, but split into two commands such that work between the two may execute unhindered.

Note

Applications should be careful to avoid race conditions when using events. There is no direct ordering guarantee between a vkCmdResetEvent command and a vkCmdWaitEvents command submitted after it, so some other execution dependency must be included between these commands (e.g. a semaphore).

Valid Usage

srcStageMask must be the bitwise OR of the stageMask parameter used in previous calls to vkCmdSetEvent with any of the members of pEvents and VK_PIPELINE_STAGE_HOST_BIT if any of the members of pEvents was set using vkSetEvent

If the geometry shaders feature is not enabled, dstStageMask must not contain VK_PIPELINE_STAGE_GEOMETRY_SHADER_BIT
If the tessellation shaders feature is not enabled, srcStageMask must not contain VK_PIPELINE_STAGE_TESSELLATION_CONTROL_SHADER_BIT or VK_PIPELINE_STAGE_TESSELLATION_EVALUATION_SHADER_BIT
If the tessellation shaders feature is not enabled, dstStageMask must not contain VK_PIPELINE_STAGE_TESSELLATION_CONTROL_SHADER_BIT or VK_PIPELINE_STAGE_TESSELLATION_EVALUATION_SHADER_BIT
If pEvents includes one or more events that will be signaled by vkSetEvent after commandBuffer has been submitted to a queue, then vkCmdWaitEvents must not be called inside a render pass instance
Any pipeline stage included in srcStageMask or dstStageMask must be supported by the capabilities of the queue family specified by the queueFamilyIndex member of the VkCommandPoolCreateInfo structure that was used to create the VkCommandPool that commandBuffer was allocated from, as specified in the table of supported pipeline stages.
Each element of pMemoryBarriers, pBufferMemoryBarriers or pImageMemoryBarriers must not have any access flag included in its srcAccessMask member if that bit is not supported by any of the pipeline stages in srcStageMask, as specified in the table of supported access types.
Each element of pMemoryBarriers, pBufferMemoryBarriers or pImageMemoryBarriers must not have any access flag included in its dstAccessMask member if that bit is not supported by any of the pipeline stages in dstStageMask, as specified in the table of supported access types.
commandBuffer’s current device mask must include exactly one physical device.

Description

When vkCmdPipelineBarrier is submitted to a queue, it defines a memory dependency between commands that were submitted before it, and those submitted after it.

If vkCmdPipelineBarrier was recorded outside a render pass instance, the first synchronization scope includes all commands that occur earlier in submission order. If vkCmdPipelineBarrier was recorded inside a render pass instance, the first synchronization scope includes only commands that occur earlier in submission order within the same subpass. In either case, the first synchronization scope is limited to operations on the pipeline stages determined by the source stage mask specified by srcStageMask.

If vkCmdPipelineBarrier was recorded outside a render pass instance, the second synchronization scope includes all commands that occur later in submission order. If vkCmdPipelineBarrier was recorded inside a render pass instance, the second synchronization scope includes only commands that occur later in submission order within the same subpass. In either case, the second synchronization scope is limited to operations on the pipeline stages determined by the destination stage mask specified by dstStageMask.

The first access scope is limited to access in the pipeline stages determined by the source stage mask specified by srcStageMask. Within that, the first access scope only includes the first access scopes defined by elements of the pMemoryBarriers, pBufferMemoryBarriers and pImageMemoryBarriers arrays, which each define a set of memory barriers. If no memory barriers are specified, then the first access scope includes no accesses.

The second access scope is limited to access in the pipeline stages determined by the destination stage mask specified by dstStageMask. Within that, the second access scope only includes the second access scopes defined by elements of the pMemoryBarriers, pBufferMemoryBarriers and pImageMemoryBarriers arrays, which each define a set of memory barriers. If no memory barriers are specified, then the second access scope includes no accesses.

If dependencyFlags includes VK_DEPENDENCY_BY_REGION_BIT, then any dependency between framebuffer-space pipeline stages is framebuffer-local - otherwise it is framebuffer-global.

Parameters

commandBuffer is the command buffer into which this command will be recorded.

queryPool is the query pool that will manage the results of the query.
query is the query index within the query pool that will contain the results.
flags is a bitmask of VkQueryControlFlagBits specifying constraints on the types of queries that can be performed.

Description

If the queryType of the pool is VK_QUERY_TYPE_OCCLUSION and flags contains VK_QUERY_CONTROL_PRECISE_BIT, an implementation must return a result that matches the actual number of samples passed. This is described in more detail in Occlusion Queries.

After beginning a query, that query is considered active within the command buffer it was called in until that same query is ended. Queries active in a primary command buffer when secondary command buffers are executed are considered active for those secondary command buffers.

Valid Usage

queryPool must have been created with a queryType that differs from that of any queries that are active within commandBuffer

All queries used by the command must be unavailable
If the precise occlusion queries feature is not enabled, or the queryType used to create queryPool was not VK_QUERY_TYPE_OCCLUSION, flags must not contain VK_QUERY_CONTROL_PRECISE_BIT
query must be less than the number of queries in queryPool
If the queryType used to create queryPool was VK_QUERY_TYPE_OCCLUSION, the VkCommandPool that commandBuffer was allocated from must support graphics operations
If the queryType used to create queryPool was VK_QUERY_TYPE_PIPELINE_STATISTICS and any of the pipelineStatistics indicate graphics operations, the VkCommandPool that commandBuffer was allocated from must support graphics operations
If the queryType used to create queryPool was VK_QUERY_TYPE_PIPELINE_STATISTICS and any of the pipelineStatistics indicate compute operations, the VkCommandPool that commandBuffer was allocated from must support compute operations
If vkCmdBeginQuery is called within a render pass instance, the sum of query and the number of bits set in the current subpass’s view mask must be less than or equal to the number of queries in queryPool

Valid Usage (Implicit)

commandBuffer must be a valid VkCommandBuffer handle

queryPool must be a valid VkQueryPool handle
flags must be a valid combination of VkQueryControlFlagBits values
commandBuffer must be in the recording state
The VkCommandPool that commandBuffer was allocated from must support graphics, or compute operations
Both of commandBuffer, and queryPool must have been created, allocated, or retrieved from the same VkDevice

Host Synchronization

Host access to commandBuffer must be externally synchronized

Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized

Parameters

commandBuffer is the command buffer into which this command will be recorded.

queryPool is the query pool that is managing the results of the query.
query is the query index within the query pool where the result is stored.

Description

As queries operate asynchronously, ending a query does not immediately set the query’s status to available. A query is considered finished when the final results of the query are ready to be retrieved by vkGetQueryPoolResults and vkCmdCopyQueryPoolResults, and this is when the query’s status is set to available.

Once a query is ended the query must finish in finite time, unless the state of the query is changed using other commands, e.g. by issuing a reset of the query.

Valid Usage

All queries used by the command must be active

query must be less than the number of queries in queryPool
If vkCmdEndQuery is called within a render pass instance, the sum of query and the number of bits set in the current subpass’s view mask must be less than or equal to the number of queries in queryPool

Valid Usage (Implicit)

commandBuffer must be a valid VkCommandBuffer handle

queryPool must be a valid VkQueryPool handle
commandBuffer must be in the recording state
The VkCommandPool that commandBuffer was allocated from must support graphics, or compute operations
Both of commandBuffer, and queryPool must have been created, allocated, or retrieved from the same VkDevice

Host Synchronization

Host access to commandBuffer must be externally synchronized

Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized

Parameters

commandBuffer is the command buffer into which the command will be recorded.

pipelineStage is one of the VkPipelineStageFlagBits, specifying a stage of the pipeline.
queryPool is the query pool that will manage the timestamp.
query is the query within the query pool that will contain the timestamp.

Description

vkCmdWriteTimestamp latches the value of the timer when all previous commands have completed executing as far as the specified pipeline stage, and writes the timestamp value to memory. When the timestamp value is written, the availability status of the query is set to available.

Note

If an implementation is unable to detect completion and latch the timer at any specific stage of the pipeline, it may instead do so at any logically later stage.

vkCmdCopyQueryPoolResults can then be called to copy the timestamp value from the query pool into buffer memory, with ordering and synchronization behavior equivalent to how other queries operate. Timestamp values can also be retrieved from the query pool using vkGetQueryPoolResults. As with other queries, the query must be reset using vkCmdResetQueryPool before requesting the timestamp value be written to it.

While vkCmdWriteTimestamp can be called inside or outside of a render pass instance, vkCmdCopyQueryPoolResults must only be called outside of a render pass instance.

Timestamps may only be meaningfully compared if they are written by commands submitted to the same queue.

Note

An example of such a comparison is determining the execution time of a sequence of commands.

If vkCmdWriteTimestamp is called while executing a render pass instance that has multiview enabled, the timestamp uses N consecutive query indices in the query pool (starting at query) where N is the number of bits set in the view mask of the subpass the command is executed in. The resulting query values are determined by an implementation-dependent choice of one of the following behaviors:

The first query is a timestamp value and (if more than one bit is set in the view mask) zero is written to the remaining queries. If two timestamps are written in the same subpass, the sum of the execution time of all views between those commands is the difference between the first query written by each command.
All N queries are timestamp values. If two timestamps are written in the same subpass, the sum of the execution time of all views between those commands is the sum of the difference between corresponding queries written by each command. The difference between corresponding queries may be the execution time of a single view.

In either case, the application can sum the differences between all N queries to determine the total execution time.

Valid Usage

queryPool must have been created with a queryType of VK_QUERY_TYPE_TIMESTAMP

The query identified by queryPool and query must be unavailable
The command pool’s queue family must support a non-zero timestampValidBits
All queries used by the command must be unavailable
If vkCmdWriteTimestamp is called within a render pass instance, the sum of query and the number of bits set in the current subpass’s view mask must be less than or equal to the number of queries in queryPool

Valid Usage (Implicit)

commandBuffer must be a valid VkCommandBuffer handle

pipelineStage must be a valid VkPipelineStageFlagBits value
queryPool must be a valid VkQueryPool handle
commandBuffer must be in the recording state
The VkCommandPool that commandBuffer was allocated from must support transfer, graphics, or compute operations
Both of commandBuffer, and queryPool must have been created, allocated, or retrieved from the same VkDevice

+-----------------+-----------------+-----------------+-----------------+

Parameters

commandBuffer is the command buffer into which this command will be recorded.

queryPool is the query pool managing the queries containing the desired results.
firstQuery is the initial query index.
queryCount is the number of queries. firstQuery and queryCount together define a range of queries.
dstBuffer is a VkBuffer object that will receive the results of the copy command.
dstOffset is an offset into dstBuffer.
stride is the stride in bytes between results for individual queries within dstBuffer. The required size of the backing memory for dstBuffer is determined as described above for vkGetQueryPoolResults.
flags is a bitmask of VkQueryResultFlagBits specifying how and when results are returned.

Description

vkCmdCopyQueryPoolResults is guaranteed to see the effect of previous uses of vkCmdResetQueryPool in the same queue, without any additional synchronization. Thus, the results will always reflect the most recent use of the query.

flags has the same possible values described above for the flags parameter of vkGetQueryPoolResults, but the different style of execution causes some subtle behavioral differences. Because vkCmdCopyQueryPoolResults executes in order with respect to other query commands, there is less ambiguity about which use of a query is being requested.

If no bits are set in flags, results for all requested queries in the available state are written as 32-bit unsigned integer values, and nothing is written for queries in the unavailable state.

If VK_QUERY_RESULT_64_BIT is set, the results are written as an array of 64-bit unsigned integer values as described for vkGetQueryPoolResults.

If VK_QUERY_RESULT_WAIT_BIT is set, the implementation will wait for each query’s status to be in the available state before retrieving the numerical results for that query. This is guaranteed to reflect the most recent use of the query on the same queue, assuming that the query is not being simultaneously used by other queues. If the query does not become available in a finite amount of time (e.g. due to not issuing a query since the last reset), a VK_ERROR_DEVICE_LOST error may occur.

Similarly, if VK_QUERY_RESULT_WITH_AVAILABILITY_BIT is set and VK_QUERY_RESULT_WAIT_BIT is not set, the availability is guaranteed to reflect the most recent use of the query on the same queue, assuming that the query is not being simultaneously used by other queues. As with vkGetQueryPoolResults, implementations must guarantee that if they return a non-zero availability value, then the numerical results are valid.

If VK_QUERY_RESULT_PARTIAL_BIT is set, VK_QUERY_RESULT_WAIT_BIT is not set, and the query’s status is unavailable, an intermediate result value between zero and the final result value is written for that query.

VK_QUERY_RESULT_PARTIAL_BIT must not be used if the pool’s queryType is VK_QUERY_TYPE_TIMESTAMP.

vkCmdCopyQueryPoolResults is considered to be a transfer operation, and its writes to buffer memory must be synchronized using VK_PIPELINE_STAGE_TRANSFER_BIT and VK_ACCESS_TRANSFER_WRITE_BIT before using the results.

Valid Usage

dstOffset must be less than the size of dstBuffer

firstQuery must be less than the number of queries in queryPool
The sum of firstQuery and queryCount must be less than or equal to the number of queries in queryPool
If VK_QUERY_RESULT_64_BIT is not set in flags then dstOffset and stride must be multiples of 4
If VK_QUERY_RESULT_64_BIT is set in flags then dstOffset and stride must be multiples of 8
dstBuffer must have enough storage, from dstOffset, to contain the result of each query, as described here
dstBuffer must have been created with VK_BUFFER_USAGE_TRANSFER_DST_BIT usage flag
If dstBuffer is non-sparse then it must be bound completely and contiguously to a single VkDeviceMemory object
If the queryType used to create queryPool was VK_QUERY_TYPE_TIMESTAMP, flags must not contain VK_QUERY_RESULT_PARTIAL_BIT

Valid Usage (Implicit)

commandBuffer must be a valid VkCommandBuffer handle

queryPool must be a valid VkQueryPool handle
dstBuffer must be a valid VkBuffer handle
flags must be a valid combination of VkQueryResultFlagBits values

Parameters

commandBuffer is the command buffer in which to record the command.

contents specifies how the commands in the next subpass will be provided, in the same fashion as the corresponding parameter of vkCmdBeginRenderPass.

Description

The subpass index for a render pass begins at zero when vkCmdBeginRenderPass is recorded, and increments each time vkCmdNextSubpass is recorded.

Moving to the next subpass automatically performs any multisample resolve operations in the subpass being ended. End-of-subpass multisample resolves are treated as color attachment writes for the purposes of synchronization. That is, they are considered to execute in the VK_PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT pipeline stage and their writes are synchronized with VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT. Synchronization between rendering within a subpass and any resolve operations at the end of the subpass occurs automatically, without need for explicit dependencies or pipeline barriers. However, if the resolve attachment is also used in a different subpass, an explicit dependency is needed.

After transitioning to the next subpass, the application can record the commands for that subpass.

Valid Usage

The current subpass index must be less than the number of subpasses in the render pass minus one

Valid Usage (Implicit)

commandBuffer must be a valid VkCommandBuffer handle

contents must be a valid VkSubpassContents value
commandBuffer must be in the recording state
The VkCommandPool that commandBuffer was allocated from must support graphics operations

The second access scope is limited to access to memory through the specified buffer range, via access types in the destination access mask. specified by dstAccessMask. If dstAccessMask includes VK_ACCESS_HOST_WRITE_BIT or VK_ACCESS_HOST_READ_BIT, available memory writes are also made visible to accesses of those types, as those access types are not performed through a resource.

Description

The first access scope is limited to access to memory through the specified image subresource range, via access types in the source access mask specified by srcAccessMask. If srcAccessMask includes VK_ACCESS_HOST_WRITE_BIT, memory writes performed by that access type are also made visible, as that access type is not performed through a resource.

The second access scope is limited to access to memory through the specified image subresource range, via access types in the destination access mask specified by dstAccessMask. If dstAccessMask includes VK_ACCESS_HOST_WRITE_BIT or VK_ACCESS_HOST_READ_BIT, available memory writes are also made visible to accesses of those types, as those access types are not performed through a resource.

If srcQueueFamilyIndex is not equal to dstQueueFamilyIndex, and srcQueueFamilyIndex is equal to the current queue family, then the memory barrier defines a queue family release operation for the specified image subresource range, and the second access scope includes no access, as if dstAccessMask was 0.

If dstQueueFamilyIndex is not equal to srcQueueFamilyIndex, and dstQueueFamilyIndex is equal to the current queue family, then the memory barrier defines a queue family acquire operation for the specified image subresource range, and the first access scope includes no access, as if srcAccessMask was 0.

If oldLayout is not equal to newLayout, then the memory barrier defines an image layout transition for the specified image subresource range.

Layout transitions that are performed via image memory barriers execute in their entirety in submission order, relative to other image layout transitions submitted to the same queue, including those performed by render passes. In effect there is an implicit execution dependency from each such layout transition to all layout transitions previously submitted to the same queue.

The image layout of each image subresource of a depth/stencil image created with VK_IMAGE_CREATE_SAMPLE_LOCATIONS_COMPATIBLE_DEPTH_BIT_EXT is dependent on the last sample locations used to render to the image subresource as a depth/stencil attachment, thus when the image member of an VkImageMemoryBarrier is an image created with this flag the application can chain a VkSampleLocationsInfoEXT structure to the pNext chain of VkImageMemoryBarrier to specify the sample locations to use during the image layout transition.

If the VkSampleLocationsInfoEXT structure in the pNext chain of VkImageMemoryBarrier does not match the sample location state last used to render to the image subresource range specified by subresourceRange or if no VkSampleLocationsInfoEXT structure is in the pNext chain of VkImageMemoryBarrier then the contents of the given image subresource range becomes undefined as if oldLayout would equal VK_IMAGE_LAYOUT_UNDEFINED.

If image has a multi-planar format and the image is disjoint, then including VK_IMAGE_ASPECT_COLOR_BIT in the aspectMask member of subresourceRange is equivalent to including VK_IMAGE_ASPECT_PLANE_0_BIT, VK_IMAGE_ASPECT_PLANE_1_BIT, and (for three-plane formats only) VK_IMAGE_ASPECT_PLANE_2_BIT.

Description

For VK_IMAGE_TYPE_3D images, copies are performed slice by slice starting with the z member of the srcOffset or dstOffset, and copying depth slices. For images with multiple layers, copies are performed layer by layer starting with the baseArrayLayer member of the srcSubresource or dstSubresource and copying layerCount layers. Image data can be copied between images with different image types. If one image is VK_IMAGE_TYPE_3D and the other image is VK_IMAGE_TYPE_2D with multiple layers, then each slice is copied to or from a different layer.

Copies involving a multi-planar image format specify the region to be copied in terms of the plane to be copied, not the coordinates of the multi-planar image. This means that copies accessing the R/B planes of “_422” format images must fit the copied region within half the width of the parent image, and that copies accessing the R/B planes of “_420” format images must fit the copied region within half the width and height of the parent image.

Description

When copying to or from a depth or stencil aspect, the data in buffer memory uses a layout that is a (mostly) tightly packed representation of the depth or stencil data. Specifically:

data copied to or from the stencil aspect of any depth/stencil format is tightly packed with one VK_FORMAT_S8_UINT value per texel.
data copied to or from the depth aspect of a VK_FORMAT_D16_UNORM or VK_FORMAT_D16_UNORM_S8_UINT format is tightly packed with one VK_FORMAT_D16_UNORM value per texel.
data copied to or from the depth aspect of a VK_FORMAT_D32_SFLOAT or VK_FORMAT_D32_SFLOAT_S8_UINT format is tightly packed with one VK_FORMAT_D32_SFLOAT value per texel.
data copied to or from the depth aspect of a VK_FORMAT_X8_D24_UNORM_PACK32 or VK_FORMAT_D24_UNORM_S8_UINT format is packed with one 32-bit word per texel with the D24 value in the LSBs of the word, and undefined values in the eight MSBs.

Note

To copy both the depth and stencil aspects of a depth/stencil format, two entries in pRegions can be used, where one specifies the depth aspect in imageSubresource, and the other specifies the stencil aspect.

Because depth or stencil aspect buffer to image copies may require format conversions on some implementations, they are not supported on queues that do not support graphics. When copying to a depth aspect, the data in buffer memory must be in the the range [0,1] or undefined results occur.

Copies are done layer by layer starting with image layer baseArrayLayer member of imageSubresource. layerCount layers are copied from the source image or to the destination image.

dstSubresource must be a valid VkImageSubresourceLayers structure

Description

renderArea is the render area that is affected by the render pass instance. The effects of attachment load, store and multisample resolve operations are restricted to the pixels whose x and y coordinates fall within the render area on all attachments. The render area extends to all layers of framebuffer. The application must ensure (using scissor if necessary) that all rendering is contained within the render area, otherwise the pixels outside of the render area become undefined and shader side effects may occur for fragments outside the render area. The render area must be contained within the framebuffer dimensions.

When multiview is enabled, the resolve operation at the end of a subpass applies to all views in the view mask.

Note

There may be a performance cost for using a render area smaller than the framebuffer, unless it matches the render area granularity for the render pass.

Valid Usage

clearValueCount must be greater than the largest attachment index in renderPass that specifies a loadOp (or stencilLoadOp, if the attachment has a depth/stencil format) of VK_ATTACHMENT_LOAD_OP_CLEAR

If clearValueCount is not 0, pClearValues must be a valid pointer to an array of clearValueCount valid VkClearValue unions
renderPass must be compatible with the renderPass member of the VkFramebufferCreateInfo structure specified when creating framebuffer.

Valid Usage (Implicit)

sType must be VK_STRUCTURE_TYPE_RENDER_PASS_BEGIN_INFO

Each pNext member of any structure (including this one) in the pNext chain must be either NULL or a pointer to a valid instance of VkDeviceGroupRenderPassBeginInfo or VkRenderPassSampleLocationsBeginInfoEXT
Each sType member in the pNext chain must be unique
renderPass must be a valid VkRenderPass handle
framebuffer must be a valid VkFramebuffer handle
Both of framebuffer, and renderPass must have been created, allocated, or retrieved from the same VkDevice

Description

Valid Usage

Unless the {html_spec_relative}#VK_EXT_depth_range_unrestricted extension is enabled depth must be between 0.0 and 1.0, inclusive

Description

No memory barriers are needed between vkCmdClearAttachments and preceding or subsequent draw or attachment clear commands in the same subpass.

The vkCmdClearAttachments command is not affected by the bound pipeline state.

Attachments can also be cleared at the beginning of a render pass instance by setting loadOp (or stencilLoadOp) of VkAttachmentDescription to VK_ATTACHMENT_LOAD_OP_CLEAR, as described for vkCreateRenderPass.

Valid Usage

If aspectMask includes VK_IMAGE_ASPECT_COLOR_BIT, it must not include VK_IMAGE_ASPECT_DEPTH_BIT or VK_IMAGE_ASPECT_STENCIL_BIT

aspectMask must not include VK_IMAGE_ASPECT_METADATA_BIT
clearValue must be a valid VkClearValue union

Valid Usage (Implicit)

aspectMask must be a valid combination of VkImageAspectFlagBits values

aspectMask must not be 0

Description

The members of VkDrawIndirectCommand have the same meaning as the similarly named parameters of vkCmdDraw.

Valid Usage

For a given vertex buffer binding, any attribute data fetched must be entirely contained within the corresponding vertex buffer binding, as described in {html_spec_relative}#fxvertex-input

If the drawIndirectFirstInstance feature is not enabled, firstInstance must be 0

Description

The members of VkDrawIndexedIndirectCommand have the same meaning as the similarly named parameters of vkCmdDrawIndexed.

Valid Usage

For a given vertex buffer binding, any attribute data fetched must be entirely contained within the corresponding vertex buffer binding, as described in {html_spec_relative}#fxvertex-input

(indexSize * (firstIndex + indexCount) + offset) must be less than or equal to the size of the bound index buffer, with indexSize being based on the type specified by indexType, where the index buffer, indexType, and offset are specified via vkCmdBindIndexBuffer
If the drawIndirectFirstInstance feature is not enabled, firstInstance must be 0

Description

The members of VkDispatchIndirectCommand have the same meaning as the corresponding parameters of vkCmdDispatch.

Valid Usage

x must be less than or equal to VkPhysicalDeviceLimits::maxComputeWorkGroupCount[0]

y must be less than or equal to VkPhysicalDeviceLimits::maxComputeWorkGroupCount[1]
z must be less than or equal to VkPhysicalDeviceLimits::maxComputeWorkGroupCount[2]

Description

The four array elements of the clear color map to R, G, B, and A components of image formats, in order.

If the image has more than one sample, the same value is written to all samples for any pixels being cleared.

Description

This union is used where part of the API requires either color or depth/stencil clear values, depending on the attachment, and defines the initial clear values in the VkRenderPassBeginInfo structure.

Valid Usage

depthStencil must be a valid VkClearDepthStencilValue structure

Description

VkStencilFaceFlags is a bitmask type for setting a mask of zero or more VkStencilFaceFlagBits.
