Module contains 

Topological containment queries: “is this point inside this face/shell?” — distinct from crate::contains, which tests raw-geometry (“does this 3-D point lie on this NURBS surface/curve”) without any awareness of trimming loops or topology.

Modules

face

rng

A tiny, seedable, deterministic PRNG for picking random ray directions in containment queries — no external rand dependency.

shell

Point-in-solid containment via ray casting against a shell’s vertices, edges, and faces in 3-D — the 3-D analog of super::face::face_contains.
