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

This structure describes the following feature:

Description

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • 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 the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

  • VUID-VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FRAGMENT_SHADER_BARYCENTRIC_FEATURES_NV
