C Specification
The VkPhysicalDeviceShadingRateImagePropertiesNV
structure is defined
as:
// Provided by VK_NV_shading_rate_image
typedef struct VkPhysicalDeviceShadingRateImagePropertiesNV {
VkStructureType sType;
void* pNext;
VkExtent2D shadingRateTexelSize;
uint32_t shadingRatePaletteSize;
uint32_t shadingRateMaxCoarseSamples;
} VkPhysicalDeviceShadingRateImagePropertiesNV;
Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this 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.
Description
If the VkPhysicalDeviceShadingRateImagePropertiesNV
structure is included in the pNext
chain of the
VkPhysicalDeviceProperties2 structure passed to
vkGetPhysicalDeviceProperties2, it is filled in with each
corresponding implementation-dependent property.
These properties are related to the shading rate image feature.
