DescriptionWe introduce an algorithm to convert a self-intersection free, orientable, and manifold triangle mesh into a generalized prismatic shell equipped with a bijective projection operator to map the triangle mesh to a class of discrete surfaces contained within the shell whose normals satisfy a simple local condition. Properties can be robustly and efficiently transferred between these surfaces using the prismatic layer as a common parametrization domain.

The combination of the prismatic shell construction and corresponding projection operator is a robust building block readily usable in many downstream applications, including the solution of PDEs on surfaces, displacement maps synthesis, Boolean operations, tetrahedral meshing, geometric textures, collision proxies, and animation cages.
