C Specification

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

// Provided by VK_VERSION_1_3
void vkCmdSetRasterizerDiscardEnable(
    VkCommandBuffer                             commandBuffer,
    VkBool32                                    rasterizerDiscardEnable);

or the equivalent command

// Provided by VK_EXT_extended_dynamic_state2, VK_EXT_shader_object
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:

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
