VkCoarseSampleLocationNV

Structure specifying parameters controlling shading rate image usage

The VkCoarseSampleLocationNV structure identifies a specific pixel and sample index for one of the coverage samples in a fragment that is larger than one pixel. This structure is defined as:

typedef struct VkCoarseSampleLocationNV {
    uint32_t pixelX;
    uint32_t pixelY;
    uint32_t sample;
} VkCoarseSampleLocationNV;
  • pixelX is added to the x coordinate of the upper-leftmost pixel of each fragment to identify the pixel containing the coverage sample.
  • pixelY is added to the y coordinate of the upper-leftmost pixel of each fragment to identify the pixel containing the coverage sample.
  • sample is the number of the coverage sample in the pixel identified by pixelX and pixelY.

Valid Usage

VUID-VkCoarseSampleLocationNV-pixelX-02078

pixelX must be less than the width (in pixels) of the fragment

VUID-VkCoarseSampleLocationNV-pixelY-02079

pixelY must be less than the height (in pixels) of the fragment

VUID-VkCoarseSampleLocationNV-sample-02080

sample must be less than the number of coverage samples in each pixel belonging to the fragment
