VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR

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

The VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR structure is defined as:

typedef struct VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR {
    VkStructureType sType;
    void* pNext;
    VkBool32 fragmentShaderBarycentric;
} VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR;

or the equivalent

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. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)
