C Specification

The VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR structure is defined as:

// Provided by VK_KHR_fragment_shader_barycentric
typedef struct VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           fragmentShaderBarycentric;
} VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR;

or the equivalent

// Provided by VK_NV_fragment_shader_barycentric
typedef VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR VkPhysicalDeviceFragmentShaderBarycentricFeaturesNV;


This structure describes the following feature:

  • sType is a VkStructureType value identifying this structure.

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

  • fragmentShaderBarycentric indicates that the implementation supports the BaryCoordKHR and BaryCoordNoPerspKHR SPIR-V fragment shader built-ins and supports the PerVertexKHR SPIR-V decoration on fragment shader input variables.


See Barycentric Interpolation for more information.

If the VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR 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. VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR-sType-sType
