C Specification

To dynamically control whether primitives are discarded before the rasterization stage:

// Provided by VK_EXT_extended_dynamic_state2
void vkCmdSetRasterizerDiscardEnableEXT(
    VkCommandBuffer                             commandBuffer,
    VkBool32                                    rasterizerDiscardEnable);

Parameters

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

  • rasterizerDiscardEnable controls whether primitives are discarded immediately before the rasterization stage.

Description

This command sets the state for a given draw when the graphics pipeline is created with VK_DYNAMIC_STATE_RASTERIZER_DISCARD_ENABLE_EXT set in VkPipelineDynamicStateCreateInfo::pDynamicStates.

Valid Usage
Valid Usage (Implicit)
  • VUID-vkCmdSetRasterizerDiscardEnableEXT-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdSetRasterizerDiscardEnableEXT-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdSetRasterizerDiscardEnableEXT-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support graphics operations

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

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