C Specification

To dynamically set the representativeFragmentTestEnable state, call:

// Provided by VK_EXT_extended_dynamic_state3 with VK_NV_representative_fragment_test, VK_EXT_shader_object with VK_NV_representative_fragment_test
void vkCmdSetRepresentativeFragmentTestEnableNV(
    VkCommandBuffer                             commandBuffer,
    VkBool32                                    representativeFragmentTestEnable);


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

  • representativeFragmentTestEnable specifies the representativeFragmentTestEnable state.


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

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

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

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

  • VUID-vkCmdSetRepresentativeFragmentTestEnableNV-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
