Description
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.
New Enum Constants
New Variable Decoration
New SPIR-V Capabilities
