Function Documentation

BuildGaussianBlurModule()

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

(

)

Runs one Gaussian or box-blur pass with transparent, duplicate, or wrap sampling.

The host bounds finite sigma to [0,256] and each box extent to [0,240] through filter admission, and supplies equally sized source/destination textures. Gaussian support is capped at 127 pixels. The optional output clip is applied after sampling, before the shared [0,1] output clamp.
