R_LoadObjModel_()

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.

Definition at line 323 of file r_model_obj.cpp.

R_LoadObjModelFace()

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.
