## Name

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

Loading… please wait.

## 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;

## 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 `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`
