bool OBJFace::process_index (  long  index, unsigned long  max_val, vector< unsigned long > &  index_list )  [private]

Process a vertex position, texture coordinate or normal index to see if it is valid and, if so, to normalize it and add it to the given vector. Parameters: [in]  index  The index to check and add (if the check succeeds). [in]  max_val  The maximum value that the index can take (this should be equal to the number of elements (vertices, texture coordinates, or normals) that have been read in the .obj file at the time this face is read. [in,out]  index_list  The vector of indices to add the vertex to if it is valid. Returns: true if the index is valid and false otherwise. Definition at line 348 of file objreader.C. Referenced by add_normal(), add_texcoord(), and add_vertex().
