VkPipelineCoverageToColorStateCreateInfoNV - Structure specifying whether fragment coverage replaces a color
Description
If coverageToColorEnable is VK_TRUE, the fragment coverage
information is treated as a bitmask with one bit for each sample (as in
the Sample
Mask
section), and this bitmask replaces the first component of the color
value corresponding to the fragment shader output location with
Location equal to coverageToColorLocation and Index equal to zero.
If the color attachment format has fewer bits than the sample coverage,
the low bits of the sample coverage bitmask are taken without any
clamping. If the color attachment format has more bits than the sample
coverage, the high bits of the sample coverage bitmask are filled with
zeros.
If Sample Shading is in use, the coverage bitmask only has bits set for samples that correspond to the fragment shader invocation that shades those samples.
This pipeline stage occurs after sample counting and before blending,
and is always performed after fragment shading regardless of the setting
of EarlyFragmentTests.
If coverageToColorEnable is VK_FALSE, these operations are skipped.
If this structure is not present, it is as if coverageToColorEnable is
VK_FALSE.
Valid Usage
- If
coverageToColorEnableisVK_TRUE, then the render pass subpass indicated byVkGraphicsPipelineCreateInfo::renderPassandVkGraphicsPipelineCreateInfo::subpassmust have a color attachment at the location selected bycoverageToColorLocation, with aVkFormatofVK_FORMAT_R8_UINT,VK_FORMAT_R8_SINT,VK_FORMAT_R16_UINT,VK_FORMAT_R16_SINT,VK_FORMAT_R32_UINT, orVK_FORMAT_R32_SINT
