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;


The members of the VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV structure describe the following features:


  • 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)
  • VUID-VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV-sType-sType
