Description
This extension adds support for the following SPIR-V extension in Vulkan:
SPV_KHR_post_depth_coverage
which allows the fragment shader to control whether values in the
SampleMask
built-in input variable
reflect the coverage after early
depth
and
stencil
tests are applied.
This extension adds a new PostDepthCoverage
execution mode under the
SampleMaskPostDepthCoverage
capability. When this mode is specified
along with EarlyFragmentTests
, the value of an input variable
decorated with the
https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#interfaces-builtin-variables-samplemask
built-in reflects the coverage after the
early fragment tests
are applied. Otherwise, it reflects the coverage before the depth and
stencil tests.
When using GLSL source-based shading languages, the
post_depth_coverage
layout qualifier from GL_ARB_post_depth_coverage
or GL_EXT_post_depth_coverage maps to the PostDepthCoverage
execution
mode.
