public final class EXTPostDepthCoverage extends java.lang.Object
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 the early per-fragment depth and stencil tests are applied.This extension adds a new
PostDepthCoverage
execution mode under theSampleMaskPostDepthCoverage
capability. When this mode is specified along withEarlyFragmentTests
, the value of an input variable decorated with theSampleMask
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 thePostDepthCoverage
execution mode.- Name String
