Class VkCoarseSampleOrderCustomNV

  • All Implemented Interfaces:
    java.lang.AutoCloseable, NativeResource, Pointer

    public class VkCoarseSampleOrderCustomNV
    extends Struct
    implements NativeResource
    Structure specifying parameters controlling shading rate image usage.
    Description

    When using a custom sample ordering, element i in pSampleLocations specifies a specific pixel and per-pixel coverage sample number that corresponds to the coverage sample numbered i in the multi-pixel fragment.

    Valid Usage
    • shadingRate must be a shading rate that generates fragments with more than one pixel.
    • sampleCount must correspond to a sample count enumerated in VkSampleCountFlags whose corresponding bit is set in VkPhysicalDeviceLimits::framebufferNoAttachmentsSampleCounts.
    • sampleLocationCount must be equal to the product of sampleCount, the fragment width for shadingRate, and the fragment height for shadingRate.
    • sampleLocationCount must be less than or equal to the value of VkPhysicalDeviceShadingRateImagePropertiesNV::shadingRateMaxCoarseSamples.
    • The array pSampleLocations must contain exactly one entry for every combination of valid values for pixelX, pixelY, and sample in the structure VkCoarseSampleOrderCustomNV.
    Valid Usage (Implicit)
    • shadingRate must be a valid VkShadingRatePaletteEntryNV value
    • pSampleLocations must be a valid pointer to an array of sampleLocationCount VkCoarseSampleLocationNV structures
    • sampleLocationCount must be greater than 0

    Member documentation

    • shadingRate – a shading rate palette entry that identifies the fragment width and height for the combination of fragment area and per-pixel coverage sample count to control.
    • sampleCount – identifies the per-pixel coverage sample count for the combination of fragment area and coverage sample count to control.
    • sampleLocationCount – specifies the number of sample locations in the custom ordering.
    • pSampleLocations – a pointer to an array of VkCoarseSampleOrderCustomNV structures that specifies the location of each sample in the custom ordering.
