vkCmdSetProvokingVertexModeEXT(3)

C Specification

To dynamically set the provokingVertexMode state, call:

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

Parameters

commandBuffer is the command buffer into which the command will be recorded.
provokingVertexMode specifies the provokingVertexMode state.

Description

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
- The shaderObject 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
