Description

This extension allows the fragment coverage value, represented as an integer bitmask, to be substituted for a color output being written to a single-component color attachment with integer components (e.g. FORMAT_R8_UINT). The functionality provided by this extension is different from simply writing the SampleMask fragment shader output, in that the coverage value written to the framebuffer is taken after stencil test and depth test, as well as after fragment operations such as alpha-to-coverage.

This functionality may be useful for deferred rendering algorithms, where the second pass needs to know which samples belong to which original fragments.

VkPipelineCoverageToColorStateCreateInfoNV - Structure specifying whether fragment coverage replaces a color

Description

If the pNext chain of PipelineMultisampleStateCreateInfo includes a PipelineCoverageToColorStateCreateInfoNV structure, then that structure controls whether the fragment coverage is substituted for a fragment color output and, if so, which output is replaced.

If coverageToColorEnable is TRUE, the coverage mask 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 coverage mask, the low bits of the sample coverage mask are taken without any clamping. If the color attachment format has more bits than the coverage mask, the high bits of the sample coverage mask are filled with zeros.

If coverageToColorEnable is FALSE, these operations are skipped. If this structure is not present, it is as if coverageToColorEnable is FALSE.
