vkCmdSetProvokingVertexModeEXT

Specify the provoking vertex mode dynamically for a command buffer
primary / secondary
both
graphics
state

To dynamically set the provokingVertexMode state, call:

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:- The extendedDynamicState3ProvokingVertexMode feature is enabled

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 ::
