Detailed Description

A single face in a mesh, referring to multiple vertices.

If mNumIndices is 3, we call the face triangle, for for mNumIndices > 3 it's called polygon.

aiMesh.mPrimitiveTypes can be queried to quickly examine which types of primitive are actually present in a mesh. The aiProcess.SortByPType flag post-processing step splits meshes containing different primitive types (e.g. lines and triangles) in several "clean" submeshes.

Furthermore, there is a configuration option (AI_CONFIG_PP_SBP_REMOVE) to force SortByPType to completely remove specific kinds of primitives from the imported scene. In many cases you'll probably want to set this setting to aiPrimitiveType.LINE | aiPrimitiveType.POINT. Together with the aiProcess.Triangulate flag you can then be sure that mNumIndices is always 3.
