## Name

VkPhysicalDeviceFragmentShadingRateEnumsFeaturesNV - Structure indicating support for fragment shading rate enums

Loading… please wait.

## C Specification

The `VkPhysicalDeviceFragmentShadingRateEnumsFeaturesNV` structure is defined as:

    // Provided by VK_NV_fragment_shading_rate_enums
    typedef struct VkPhysicalDeviceFragmentShadingRateEnumsFeaturesNV {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           fragmentShadingRateEnums;
        VkBool32           supersampleFragmentShadingRates;
        VkBool32           noInvocationFragmentShadingRates;
    } VkPhysicalDeviceFragmentShadingRateEnumsFeaturesNV;

## Members

This structure describes the following features:

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `fragmentShadingRateEnums` indicates that the implementation supports specifying fragment shading rates using the `VkFragmentShadingRateNV` enumerated type.

- `supersampleFragmentShadingRates` indicates that the implementation supports fragment shading rate enum values indicating more than one invocation per fragment.

- `noInvocationFragmentShadingRates` indicates that the implementation supports a fragment shading rate enum value indicating that no fragment shaders should be invoked when that shading rate is used.

## Description

If the `VkPhysicalDeviceFragmentShadingRateEnumsFeaturesNV` 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 `VkPhysicalDeviceFragmentShadingRateEnumsFeaturesNV`, 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)

- VUID-VkPhysicalDeviceFragmentShadingRateEnumsFeaturesNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FRAGMENT_SHADING_RATE_ENUMS_FEATURES_NV`
