C Specification

The VkPhysicalDeviceShadingRateImagePropertiesNV structure is defined as:

typedef struct VkPhysicalDeviceShadingRateImagePropertiesNV {
    VkStructureType    sType;
    void*              pNext;
    VkExtent2D         shadingRateTexelSize;
    uint32_t           shadingRatePaletteSize;
    uint32_t           shadingRateMaxCoarseSamples;
} VkPhysicalDeviceShadingRateImagePropertiesNV;

Members

The members of the VkPhysicalDeviceShadingRateImagePropertiesNV structure describe the following implementation-dependent properties related to the shading rate image feature:

Description

  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • shadingRateTexelSize indicates the width and height of the portion of the framebuffer corresponding to each texel in the shading rate image.

  • shadingRatePaletteSize indicates the maximum number of palette entries supported for the shading rate image.

  • shadingRateMaxCoarseSamples specifies the maximum number of coverage samples supported in a single fragment. If the product of the fragment size derived from the base shading rate and the number of coverage samples per pixel exceeds this limit, the final shading rate will be adjusted so that its product does not exceed the limit.

If the VkPhysicalDeviceShadingRateImagePropertiesNV structure is included in the pNext chain of VkPhysicalDeviceProperties2, it is filled with the implementation-dependent limits.

Valid Usage (Implicit)
  • sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADING_RATE_IMAGE_PROPERTIES_NV
