public final class NVFragmentShaderBarycentric extends java.lang.Object
This extension adds support for the following SPIR-V extension in Vulkan:The extension provides access to three additional fragment shader variable decorations in SPIR-V:
PerVertexNV
, which indicates that a fragment shader input will not have interpolated values, but instead must be accessed with an extra array index that identifies one of the vertices of the primitive producing the fragmentBaryCoordNV
, which indicates that the variable is a three-component floating-point vector holding barycentric weights for the fragment produced using perspective interpolationBaryCoordNoPerspNV
, which indicates that the variable is a three-component floating-point vector holding barycentric weights for the fragment produced using linear interpolation
When using GLSL source-based shader languages, the following variables from
GL_NV_fragment_shader_barycentric
maps to these SPIR-V built-in decorations:in vec3 gl_BaryCoordNV;
→BaryCoordNV
in vec3 gl_BaryCoordNoPerspNV;
→BaryCoordNoPerspNV
GLSL variables declared using the
__pervertexNV
GLSL qualifier are expected to be decorated withPerVertexNV
in SPIR-V.- Name String
