C Specification

The VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV structure is defined as:

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 VkPhysicalDeviceFeatures2KHR, it is filled with values indicating whether the feature is supported. VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV can also be used 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
