# VkPipelineRasterizationProvokingVertexStateCreateInfoEXT(3) Manual Page

## Name

VkPipelineRasterizationProvokingVertexStateCreateInfoEXT - Structure specifying provoking vertex mode used by a graphics pipeline

Loading… please wait.

## C Specification

For a given primitive topology, the pipeline’s provoking vertex mode determines which vertex is the provoking vertex. To specify the provoking vertex mode, include a `VkPipelineRasterizationProvokingVertexStateCreateInfoEXT` structure in the VkPipelineRasterizationStateCreateInfo::`pNext` chain when creating the pipeline.

The `VkPipelineRasterizationProvokingVertexStateCreateInfoEXT` structure is defined as:

    // Provided by VK_EXT_provoking_vertex
    typedef struct VkPipelineRasterizationProvokingVertexStateCreateInfoEXT {
        VkStructureType             sType;
        const void*                 pNext;
        VkProvokingVertexModeEXT    provokingVertexMode;
    } VkPipelineRasterizationProvokingVertexStateCreateInfoEXT;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `provokingVertexMode` is a VkProvokingVertexModeEXT value selecting the provoking vertex mode.

## Description

If this structure is not provided when creating the pipeline, the pipeline will use the `VK_PROVOKING_VERTEX_MODE_FIRST_VERTEX_EXT` mode.

If the `provokingVertexModePerPipeline` limit is `VK_FALSE`, then all pipelines bound within a render pass instance must have the same `provokingVertexMode`.

Valid Usage

- VUID-VkPipelineRasterizationProvokingVertexStateCreateInfoEXT-provokingVertexMode-04883
  If `provokingVertexMode` is `VK_PROVOKING_VERTEX_MODE_LAST_VERTEX_EXT`, then the `provokingVertexLast` feature must be enabled

Valid Usage (Implicit)

- VUID-VkPipelineRasterizationProvokingVertexStateCreateInfoEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PIPELINE_RASTERIZATION_PROVOKING_VERTEX_STATE_CREATE_INFO_EXT`

- VUID-VkPipelineRasterizationProvokingVertexStateCreateInfoEXT-provokingVertexMode-parameter
  `provokingVertexMode` must be a valid VkProvokingVertexModeEXT value
