# VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV(3) Manual Page

## Name

VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV - Structure describing barycentric support in fragment shaders that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV` structure is defined as:

    // Provided by VK_NV_fragment_shader_barycentric
    typedef struct VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           fragmentShaderBarycentric;
    } VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV;

## Members

The members of the `VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV` structure describe the following features:

## Description

- `fragmentShaderBarycentric` indicates that the implementation supports the `BaryCoordNV` and `BaryCoordNoPerspNV` SPIR-V fragment shader built-ins and supports the `PerVertexNV` SPIR-V decoration on fragment shader input variables.

See Barycentric Interpolation for more information.

If the `VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV` structure is included in the `pNext` chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether the feature is supported. `VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV` can also be included in the `pNext` chain of VkDeviceCreateInfo to enable features.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FRAGMENT_SHADER_BARYCENTRIC_FEATURES_NV`
