Class NVFragmentCoverageToColor


  • public final class NVFragmentCoverageToColor
    extends java.lang.Object
    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.
