This Elm package allows you to create and manipulate indexed triangular meshes. A mesh contains an array of vertices which contain the bulk of the mesh data; vertices can be of any type, so you can create meshes from 2D or 3D points or have complex vertices of your own custom type that include additional data such as colors, normal vectors, texture coordinates, unique IDs, etc.
Mesh faces are defined by triples of integer indices specifying which three vertices make up the face. This package has functionality for creating meshes in various ways, extracting faces as index triples or vertex triples, extracting edges as index pairs or vertex pairs, and combining multiple meshes.
Full API documentation is available.
