Description

This extension adds transform feedback to the Vulkan API by exposing the SPIR-V TransformFeedback and GeometryStreams capabilities to capture vertex, tessellation or geometry shader outputs to one or more buffers. It adds API functionality to bind transform feedback buffers to capture the primitives emitted by the graphics pipeline from SPIR-V outputs decorated for transform feedback. The transform feedback capture can be paused and resumed by way of storing and retrieving a byte counter. The captured data can be drawn again where the vertex count is derived from the byte counter without CPU intervention. If the implementation is capable, a vertex stream other than zero can be rasterized.

All these features are designed to match the full capabilities of OpenGL core transform feedback functionality and beyond. Many of the features are optional to allow base OpenGL ES GPUs to also implement this extension.

The primary purpose of the functionality exposed by this extension is to support translation layers from other 3D APIs. This functionality is not considered forward looking, and is not expected to be promoted to a KHR extension or to core Vulkan. Unless this is needed for translation, it is recommended that developers use alternative techniques of using the GPU to process and capture vertex data.

Issues

1) Should we include pause/resume functionality?

RESOLVED: Yes, this is needed to ease layering other APIs which have this functionality. To pause use cmdEndTransformFeedbackEXT and provide valid buffer handles in the pCounterBuffers array and offsets in the pCounterBufferOffsets array for the implementation to save the resume points. Then to resume use cmdBeginTransformFeedbackEXT with the previous pCounterBuffers and pCounterBufferOffsets values. Between the pause and resume there needs to be a memory barrier for the counter buffers with a source access of ACCESS_TRANSFORM_FEEDBACK_COUNTER_WRITE_BIT_EXT at pipeline stage PIPELINE_STAGE_TRANSFORM_FEEDBACK_BIT_EXT to a destination access of ACCESS_TRANSFORM_FEEDBACK_COUNTER_READ_BIT_EXT at pipeline stage PIPELINE_STAGE_TRANSFORM_FEEDBACK_BIT_EXT.

2) How does this interact with multiview?

RESOLVED: Transform feedback cannot be made active in a render pass with multiview enabled.

3) How should queries be done?

RESOLVED: There is a new query type QUERY_TYPE_TRANSFORM_FEEDBACK_STREAM_EXT. A query pool created with this type will capture 2 integers - numPrimitivesWritten and numPrimitivesNeeded - for the specified vertex stream output from the last pre-rasterization shader stage. The vertex stream output queried is zero by default, but can be specified with the new cmdBeginQueryIndexedEXT and cmdEndQueryIndexedEXT commands.

Synopsis

Documentation

cmdBindTransformFeedbackBuffersEXT Source #

Arguments

:: forall io. MonadIO io 
=> CommandBuffer

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

-> ("firstBinding" ::: Word32)

firstBinding is the index of the first transform feedback binding whose state is updated by the command.

-> ("buffers" ::: Vector Buffer)

pBuffers is a pointer to an array of buffer handles.

-> ("offsets" ::: Vector DeviceSize)

pOffsets is a pointer to an array of buffer offsets.

-> ("sizes" ::: Vector DeviceSize)

pSizes is NULL or a pointer to an array of DeviceSize buffer sizes, specifying the maximum number of bytes to capture to the corresponding transform feedback buffer. If pSizes is NULL, or the value of the pSizes array element is WHOLE_SIZE, then the maximum number of bytes captured will be the size of the corresponding buffer minus the buffer offset.

-> io () 

vkCmdBindTransformFeedbackBuffersEXT - Bind transform feedback buffers to a command buffer

Description

The values taken from elements i of pBuffers, pOffsets and pSizes replace the current state for the transform feedback binding firstBinding + i, for i in [0, bindingCount). The transform feedback binding is updated to start at the offset indicated by pOffsets[i] from the start of the buffer pBuffers[i].

Valid Usage

  • pBuffers must be a valid pointer to an array of bindingCount valid Buffer handles
  • pOffsets must be a valid pointer to an array of bindingCount DeviceSize values
  • commandBuffer must be in the recording state
  • The CommandPool that commandBuffer was allocated from must support graphics operations
  • This command must only be called outside of a video coding scope
  • bindingCount must be greater than 0
  • Both of commandBuffer, and the elements of pBuffers must have been created, allocated, or retrieved from the same Device

cmdBeginTransformFeedbackEXT Source #

Arguments

:: forall io. MonadIO io 
=> CommandBuffer

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

-> ("firstCounterBuffer" ::: Word32)

firstCounterBuffer is the index of the first transform feedback buffer corresponding to pCounterBuffers[0] and pCounterBufferOffsets[0].

-> ("counterBuffers" ::: Vector Buffer)

pCounterBuffers is NULL or a pointer to an array of Buffer handles to counter buffers. Each buffer contains a 4 byte integer value representing the byte offset from the start of the corresponding transform feedback buffer from where to start capturing vertex data. If the byte offset stored to the counter buffer location was done using cmdEndTransformFeedbackEXT it can be used to resume transform feedback from the previous location. If pCounterBuffers is NULL, then transform feedback will start capturing vertex data to byte offset zero in all bound transform feedback buffers. For each element of pCounterBuffers that is NULL_HANDLE, transform feedback will start capturing vertex data to byte zero in the corresponding bound transform feedback buffer.

-> ("counterBufferOffsets" ::: Vector DeviceSize)

pCounterBufferOffsets is NULL or a pointer to an array of DeviceSize values specifying offsets within each of the pCounterBuffers where the counter values were previously written. The location in each counter buffer at these offsets must be large enough to contain 4 bytes of data. This data is the number of bytes captured by the previous transform feedback to this buffer. If pCounterBufferOffsets is NULL, then it is assumed the offsets are zero.

-> io () 

vkCmdBeginTransformFeedbackEXT - Make transform feedback active in the command buffer

  • For each buffer handle in the array, if it is not NULL_HANDLE it must reference a buffer large enough to hold 4 bytes at the corresponding offset from the pCounterBufferOffsets array
  • If pCounterBuffer is NULL, then pCounterBufferOffsets must also be NULL
  • For each buffer handle in the pCounterBuffers array that is not NULL_HANDLE it must have been created with a usage value containing BUFFER_USAGE_TRANSFORM_FEEDBACK_COUNTER_BUFFER_BIT_EXT
  • A valid graphics pipeline must be bound to PIPELINE_BIND_POINT_GRAPHICS
  • The last pre-rasterization shader stage of the bound graphics pipeline must have been declared with the Xfb execution mode
  • Transform feedback must not be made active in a render pass instance with multiview enabled

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

-> ("firstCounterBuffer" ::: Word32)

firstCounterBuffer is the index of the first transform feedback buffer corresponding to pCounterBuffers[0] and pCounterBufferOffsets[0].

-> ("counterBuffers" ::: Vector Buffer)

pCounterBuffers is NULL or a pointer to an array of Buffer handles to counter buffers.

It can also be used by cmdDrawIndirectByteCountEXT to determine the vertex count of the draw call.

-> ("counterBufferOffsets" ::: Vector DeviceSize)

pCounterBufferOffsets is NULL or a pointer to an array of DeviceSize values specifying offsets within each of the pCounterBuffers where the counter values can be written. The location in each counter buffer at these offsets must be large enough to contain 4 bytes of data. The data stored at this location is the byte offset from the start of the transform feedback buffer binding where the next vertex data would be written. If pCounterBufferOffsets is NULL, then it is assumed the offsets are zero.

counterOffset is subtracted from the byte count read from the counterBuffer at the counterBufferOffset

-> ("vertexStride" ::: Word32)

vertexStride is the stride in bytes between each element of the vertex data that is used to calculate the vertex count from the counter value. This value is typically the same value that was used in the graphics pipeline state when the transform feedback was captured as the XfbStride.

-> io () 

vkCmdDrawIndirectByteCountEXT - Draw primitives with indirect parameters where the vertex count is derived from the counter byte value in the counter buffer

Description

When the command is executed, primitives are assembled in the same way as done with cmdDraw except the vertexCount is calculated based on the byte count read from counterBuffer at offset counterBufferOffset. The assembled primitives execute the bound graphics pipeline.

The effective vertexCount is calculated as follows:

const uint32_t * counterBufferPtr = (const uint8_t *)counterBuffer.address + counterBufferOffset;
