LaSh is a displacement-aware Material shader layering system that contains the latest reference implementation of the Layering Displaced Materials with Thickness, Accumulation, and Size paper.
Derived from the Laika Production Shading Library for RenderMan 20, LaSh incorporates bxdfs and displacements into its definition of a LaSh Material shader so that it can represent a true physical substance, and implements a bxdf and displacement-aware layering capability so LaSh Material shaders can be easily and intuitively layered over one another in a physically plausible way.
All documentation is in the doc directory.
As a bonus, this repository also contains the Siggraph 2024 Shader Writing in Open Shading Language course Supplementary Material shading nodes.
