Package org.lwjgl.vulkan

Class NVSampleMaskOverrideCoverage

java.lang.Object
org.lwjgl.vulkan.NVSampleMaskOverrideCoverage
public final class NVSampleMaskOverrideCoverage extends Object
This extension adds support for the following SPIR-V extension in Vulkan:
  • SPV_NV_sample_mask_override_coverage

The extension provides access to the OverrideCoverageNV decoration under the SampleMaskOverrideCoverageNV capability. Adding this decoration to a variable with the SampleMask builtin decoration allows the shader to modify the coverage mask and affect which samples are used to process the fragment.

When using GLSL source-based shader languages, the override_coverage layout qualifier from GL_NV_sample_mask_override_coverage maps to the OverrideCoverageNV decoration. To use the override_coverage layout qualifier in GLSL the GL_NV_sample_mask_override_coverage extension must be enabled. Behavior is described in the GL_NV_sample_mask_override_coverage extension spec.
