	Parse the object file line. If the structures have been allocated, populate them. Otherwise simply accumulate counts.

static void	R_LoadObjModel_ (model_t *mod, mobj_t *obj, const byte *buffer, int bufSize)
	Drives the actual parsing of the object file. The file is read twice: once to acquire primitive counts, and a second time to load them.

static void R_LoadObjModel_	(	model_t *	mod,
		mobj_t *	obj,
		const byte *	buffer,
		int	bufSize
	)			[static]

Drives the actual parsing of the object file. The file is read twice: once to acquire primitive counts, and a second time to load them.

static int R_LoadObjModelFace	(	const model_t *	mod,
		mobj_t *	obj,
		const char *	line
	)			[static]

Each line consists of 3 or more vertex definitions, e.g.

 57/13/31 58/14/32 59/15/33 21/15/19 

Tokenize the line with Com_Parse, and parse each vertex definition. Faces with more than 3 vertices must be broken down into triangles.

Returns:

the number of triangles produced for the specified line.
