OBJ file loader: A C++ implementation of a robust OBJ loader using a Lexical Analyzer(flex) and Parser (bison)

Author: Charalambos Poullis

This is a robust OBJ loader based on LEX for lexical analysis and YACC for parsing. I initially wrote this because of the different variations of the OBJ files available some in binary, others in ascii, some with different formats for the faces etc. This parser reads the OBJ file and puts all information in the OBJ object. You can convert that information to your own structures. If it fails to recognize a particular command it will try and recover. If it fails again it will give a syntax error. As long as the format conforms to the OBJ file format as set forth by Alias Wavefront the OBJLoader will work as expected.
