Description

This extension provides additional orthogonally aligned “discard rectangles” specified in framebuffer-space coordinates that restrict rasterization of all points, lines and triangles.

From zero to an implementation-dependent limit (specified by maxDiscardRectangles) number of discard rectangles can be operational at once. When one or more discard rectangles are active, rasterized fragments can either survive if the fragment is within any of the operational discard rectangles (DISCARD_RECTANGLE_MODE_INCLUSIVE_EXT mode) or be rejected if the fragment is within any of the operational discard rectangles (DISCARD_RECTANGLE_MODE_EXCLUSIVE_EXT mode).

These discard rectangles operate orthogonally to the existing scissor test functionality. The discard rectangles can be different for each physical device in a device group by specifying the device mask and setting discard rectangle dynamic state.

Version 2 of this extension introduces new dynamic states DYNAMIC_STATE_DISCARD_RECTANGLE_ENABLE_EXT and DYNAMIC_STATE_DISCARD_RECTANGLE_MODE_EXT, and the corresponding functions cmdSetDiscardRectangleEnableEXT and cmdSetDiscardRectangleModeEXT. Applications that use these dynamic states must ensure the implementation advertises at least specVersion 2 of this extension.

Documentation

cmdSetDiscardRectangleEXT

Arguments

:: forall io. MonadIO io

=> CommandBuffer

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

-> ("firstDiscardRectangle" ::: Word32)

firstDiscardRectangle is the index of the first discard rectangle whose state is updated by the command.

-> ("discardRectangles" ::: Vector Rect2D)

pDiscardRectangles is a pointer to an array of Rect2D structures specifying discard rectangles.

-> io ()

vkCmdSetDiscardRectangleEXT - Set discard rectangles dynamically for a command buffer

Description

The discard rectangle taken from element i of pDiscardRectangles replace the current state for the discard rectangle at index firstDiscardRectangle + i, for i in [0, discardRectangleCount).

This command sets the discard rectangles for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with DYNAMIC_STATE_DISCARD_RECTANGLE_EXT set in PipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the PipelineDiscardRectangleStateCreateInfoEXT::pDiscardRectangles values used to create the currently active pipeline.

Valid Usage

• The sum of firstDiscardRectangle and discardRectangleCount must be less than or equal to PhysicalDeviceDiscardRectanglePropertiesEXT::maxDiscardRectangles

• The x and y member of offset in each Rect2D element of pDiscardRectangles must be greater than or equal to 0
• Evaluation of (offset.x + extent.width) in each Rect2D element of pDiscardRectangles must not cause a signed integer addition overflow
• Evaluation of (offset.y + extent.height) in each Rect2D element of pDiscardRectangles must not cause a signed integer addition overflow
• If this command is recorded in a secondary command buffer with CommandBufferInheritanceViewportScissorInfoNV::viewportScissor2D enabled, then this function must not be called

Valid Usage (Implicit)

• commandBuffer must be a valid CommandBuffer handle

• pDiscardRectangles must be a valid pointer to an array of discardRectangleCount Rect2D structures
• 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
• discardRectangleCount must be greater than 0

Host Synchronization

• Host access to commandBuffer must be externally synchronized

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

cmdSetDiscardRectangleEnableEXT

Arguments

:: forall io. MonadIO io

=> CommandBuffer

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

-> ("discardRectangleEnable" ::: Bool)

discardRectangleEnable specifies whether discard rectangles are enabled or not.

-> io ()

vkCmdSetDiscardRectangleEnableEXT - Enable discard rectangles dynamically for a command buffer

Description

This command sets the discard rectangle enable for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with DYNAMIC_STATE_DISCARD_RECTANGLE_ENABLE_EXT set in PipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is implied by the PipelineDiscardRectangleStateCreateInfoEXT::discardRectangleCount value used to create the currently active pipeline, where a non-zero discardRectangleCount implicitly enables discard rectangles, otherwise they are disabled.

Valid Usage

• The VK_EXT_discard_rectangles extension must be enabled, and the implementation must support at least specVersion 2 of this extension

Valid Usage (Implicit)

• commandBuffer must be a valid CommandBuffer handle

• 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

Host Synchronization

• Host access to commandBuffer must be externally synchronized

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

vkCmdSetDiscardRectangleModeEXT - Sets the discard rectangle mode dynamically for a command buffer

Description

This command sets the discard rectangle mode for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with DYNAMIC_STATE_DISCARD_RECTANGLE_MODE_EXT set in PipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the PipelineDiscardRectangleStateCreateInfoEXT::discardRectangleMode value used to create the currently active pipeline.

Valid Usage

data PipelineDiscardRectangleStateCreateInfoEXT

VkPipelineDiscardRectangleStateCreateInfoEXT - Structure specifying discard rectangle

Description

If the DYNAMIC_STATE_DISCARD_RECTANGLE_EXT dynamic state is enabled for a pipeline, the pDiscardRectangles member is ignored. If the DYNAMIC_STATE_DISCARD_RECTANGLE_ENABLE_EXT dynamic state is not enabled for the pipeline the presence of this structure in the GraphicsPipelineCreateInfo chain, and a discardRectangleCount greater than zero, implicitly enables discard rectangles in the pipeline, otherwise discard rectangles must enabled or disabled by cmdSetDiscardRectangleEnableEXT. If the DYNAMIC_STATE_DISCARD_RECTANGLE_MODE_EXT dynamic state is enabled for the pipeline, the discardRectangleMode member is ignored, and the discard rectangle mode must be set by cmdSetDiscardRectangleModeEXT.

When this structure is included in the pNext chain of GraphicsPipelineCreateInfo, it defines parameters of the discard rectangle test. If the DYNAMIC_STATE_DISCARD_RECTANGLE_EXT dynamic state is not enabled, and this structure is not included in the pNext chain, it is equivalent to specifying this structure with a discardRectangleCount of 0.
