Detailed Description

Typed channel-driven displacement with transparent-border bilinear sampling.

Function Documentation

BuildDisplacementMapModule()

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

(

)

Builds a displacement compute program.

Inputs and output have matching extents. The map is premultiplied RGBA; RGB selectors recover straight color while the alpha selector reads alpha directly. Source samples beyond the input bounds are transparent.
