VkPhysicalDeviceShadingRateImageFeaturesNV

The VkPhysicalDeviceShadingRateImageFeaturesNV structure is defined as:

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

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.
• 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 an application-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 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 VkPhysicalDeviceShadingRateImageFeaturesNV, 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.
