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

Valid Usage (Implicit)

VUID-VkPhysicalDeviceFragmentShaderBarycentricFeaturesKHR-sType-sType

sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FRAGMENT_SHADER_BARYCENTRIC_FEATURES_KHR
