Description

Handling of 3D models in Wavefront OBJ format.

First implementation based on information from [http://www.gametutorials.com]. Written without any particular reason — I just saw some code doing so, and it seemed extremely easy, and so I decided to implement it too. And it works: we simply read "v", "vt" and "f" lines and that's all.

Later extended to handle also normal vectors and materials, based on [http://www.fileformat.info/format/wavefrontobj/] and [http://www.fileformat.info/format/material/]. Texture filename is also read from material file.
