Class EXTPostDepthCoverage

  • 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 the SampleMaskPostDepthCoverage capability. When this mode is specified along with EarlyFragmentTests, the value of an input variable decorated with the 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.
