C Specification

To dynamically set the provokingVertexMode state, call:

// Provided by VK_EXT_extended_dynamic_state3, VK_EXT_shader_object
void vkCmdSetProvokingVertexModeEXT(
    VkCommandBuffer                             commandBuffer,
    VkProvokingVertexModeEXT                    provokingVertexMode);


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

  • provokingVertexMode specifies the provokingVertexMode state.


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

Valid Usage
  • VUID-vkCmdSetProvokingVertexModeEXT-None-09423
    At least one of the following must be true:

  • VUID-vkCmdSetProvokingVertexModeEXT-provokingVertexMode-07447
    If provokingVertexMode is VK_PROVOKING_VERTEX_MODE_LAST_VERTEX_EXT, then the provokingVertexLast feature must be enabled

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

  • VUID-vkCmdSetProvokingVertexModeEXT-provokingVertexMode-parameter
    provokingVertexMode must be a valid VkProvokingVertexModeEXT value

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

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

  • VUID-vkCmdSetProvokingVertexModeEXT-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
