# VkPhysicalDeviceFragmentShaderBarycentricPropertiesKHR(3) Manual Page

## Name

VkPhysicalDeviceFragmentShaderBarycentricPropertiesKHR - Structure describing fragment shader barycentric limits of an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceFragmentShaderBarycentricPropertiesKHR` structure is defined as:

    // Provided by VK_KHR_fragment_shader_barycentric
    typedef struct VkPhysicalDeviceFragmentShaderBarycentricPropertiesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           triStripVertexOrderIndependentOfProvokingVertex;
    } VkPhysicalDeviceFragmentShaderBarycentricPropertiesKHR;

## Members

- When the provoking vertex mode is `VK_PROVOKING_VERTEX_MODE_LAST_VERTEX_EXT`, and the primitive order is odd in a triangle strip, the ordering of vertices is defined in last vertex table. `triStripVertexOrderIndependentOfProvokingVertex` equal to `VK_TRUE` indicates that the implementation ignores this and uses the vertex order defined by `VK_PROVOKING_VERTEX_MODE_FIRST_VERTEX_EXT` instead.

## Description

If the `VkPhysicalDeviceFragmentShaderBarycentricPropertiesKHR` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceFragmentShaderBarycentricPropertiesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FRAGMENT_SHADER_BARYCENTRIC_PROPERTIES_KHR`
