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.

data PipelineCoverageToColorStateCreateInfoNV Source #
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.
Valid Usage
-
If
coverageToColorEnableisTRUE, then the render pass subpass indicated byGraphicsPipelineCreateInfo::renderPassandGraphicsPipelineCreateInfo::subpassmust have a color attachment at the location selected bycoverageToColorLocation, with aFormatofFORMAT_R8_UINT,FORMAT_R8_SINT,FORMAT_R16_UINT,FORMAT_R16_SINT,FORMAT_R32_UINT, orFORMAT_R32_SINT
