A few examples are available as rendered IPython notebooks.

Quick Tour

A tour of some basic features, like inertia, viewing in notebooks, etc. Quick start

Cross Sections

How to take planar slices of a mesh, like you would for 3D printing using trimesh. Cross sections

Proximity Queries

How do do signed distance and proximity queries on meshes. Nearest point queries

Path Finding

Find a path from one mesh vertex to another, travelling along edges of the mesh. Edge graph traversal

Ray Tests

Do simple ray-mesh queries, including finding the indexes of triangles hit by rays, the locations of points hit on the mesh surface, etc. Ray queries have the same API with two available backends, one implemented with just Numpy calls, and one that requires pyembree but is 50x faster (a team at Intel wrote it).
