# VkPhysicalDeviceShadingRateImageFeaturesNV(3) Manual Page

## Name

VkPhysicalDeviceShadingRateImageFeaturesNV - Structure describing shading rate image features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceShadingRateImageFeaturesNV` structure is defined as:

    typedef struct VkPhysicalDeviceShadingRateImageFeaturesNV {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shadingRateImage;
        VkBool32           shadingRateCoarseSampleOrder;
    } VkPhysicalDeviceShadingRateImageFeaturesNV;

## Members

The members of the `VkPhysicalDeviceShadingRateImageFeaturesNV` structure describe the following features:

## Description

- `shadingRateImage` indicates that the implementation supports the use of a shading rate image to derive an effective shading rate for fragment processing. It also indicates that the implementation supports the `ShadingRateNV` SPIR-V execution mode.

- `shadingRateCoarseSampleOrder` indicates that the implementation supports a user-configurable ordering of coverage samples in fragments larger than one pixel.

See Shading Rate Image for more information.

If the `VkPhysicalDeviceShadingRateImageFeaturesNV` structure is included in the `pNext` chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether the feature is supported. `VkPhysicalDeviceShadingRateImageFeaturesNV` can also be included in the `pNext` chain of VkDeviceCreateInfo to enable features.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADING_RATE_IMAGE_FEATURES_NV`
