Prims

3D Geometry Primitives for WebGL

Constructors return objects with the keys vertices, indices, and normals. Working on adding uvs. Indices should be put into at least a Uint16Array since the number of unique vertices will be greater than 255 (Uint8Array) for most geometries. The goal is to be able to have a bunch of 3D Geometries without needing all of Three.js.

All vertice lists use hard shading for polyhedra (so each vertex is duplicated for each face).

Also contains a few meshes. These must be loaded aync.
