public class NVFragmentCoverageToColor extends java.lang.Object
Native bindings to the NV_fragment_coverage_to_color extension.This extension allows the fragment coverage value, represented as an integer bitfield, to be substituted for a color output being written to a single-component color buffer with integer components (e.g., R8UI). The capability provided by this extension is different from simply writing the gl_SampleMask fragment shader output in that the coverage value written to the framebuffer is taken after alpha test, stencil test, and depth test, as well as after the multisample 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.
