vkCmdSetRasterizerDiscardEnable

Control whether primitives are discarded before the rasterization stage dynamically for a command buffer

To dynamically enable whether primitives are discarded before the rasterization stage, call:

void vkCmdSetRasterizerDiscardEnableEXT(
    VkCommandBuffer commandBuffer,
    VkBool32 rasterizerDiscardEnable);
  • commandBuffer is the command buffer into which the command will be recorded.
  • rasterizerDiscardEnable controls whether primitives are discarded immediately before the rasterization stage.

This command sets the discard enable for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_RASTERIZER_DISCARD_ENABLE set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineRasterizationStateCreateInfo::rasterizerDiscardEnable value used to create the currently active pipeline.

Valid Usage

VUID-vkCmdSetRasterizerDiscardEnable-None-08970

At least one of the following must be true:- the extendedDynamicState2 feature is enabled

Valid Usage (Implicit)

VUID-vkCmdSetRasterizerDiscardEnable-commandBuffer-parameter

commandBuffer must be a valid VkCommandBuffer handle

VUID-vkCmdSetRasterizerDiscardEnable-commandBuffer-recording

commandBuffer must be in the recording state

VUID-vkCmdSetRasterizerDiscardEnable-commandBuffer-cmdpool

The VkCommandPool that commandBuffer was allocated from must support graphics operations

VUID-vkCmdSetRasterizerDiscardEnable-videocoding

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 VkCommandPool that commandBuffer was allocated from must be externally synchronized ::
