Detailed Description
template<typename T>
class cgv::media::mesh::obj_reader_generic< T >
implements the pure reading of an obj file and calls virtual callback functions to allow a derived class to handle the read information. The default implementations of the processing methods are implemented to simply ignore the read information.
