Detailed Description

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

If mNumIndices is 3, we call the face 'triangle', for mNumIndices > 3 it's called 'polygon' (hey, that's just a definition!).
aiMesh::mPrimitiveTypes can be queried to quickly examine which types of primitive are actually present in a mesh. The aiProcess_SortByPType flag executes a special post-processing algorithm which splits meshes with *different* primitive types mixed up (e.g. lines and triangles) in several 'clean' submeshes. Furthermore there is a configuration option ( AI_CONFIG_PP_SBP_REMOVE) to force aiProcess_SortByPType to remove specific kinds of primitives from the imported scene, completely and forever. 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 aiFace::mNumIndices is always 3.

Note:

Take a look at the Data Structures page for more information on the layout and winding order of a face.
