Package org.lwjgl.vulkan
Class NVSampleMaskOverrideCoverage
java.lang.Object
org.lwjgl.vulkan.NVSampleMaskOverrideCoverage
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.
