Function Documentation

BuildDiffuseLightingModule()

ShaderResult< IrModule > donner::gpu::shader::programs::BuildDiffuseLightingModule

(

)

Builds Lambertian diffuse lighting over the input alpha height map.

The program supports distant, point, and spot lights, including transformed spotlight cones and independently bounded sampling subregions.

BuildSpecularLightingModule()

ShaderResult< IrModule > donner::gpu::shader::programs::BuildSpecularLightingModule

(

)

Builds Phong specular lighting over the input alpha height map.

The program shares light-source, normal-reconstruction, and sampling behavior with the diffuse program and writes the largest color channel as alpha.
