Detailed Description

Macro Definition Documentation

◆ RETROGLU_OBJ_TOKENS

#define RETROGLU_OBJ_TOKENS ( f )

Value:

   f( "v", retroglu_token_vertice ) \
   f( "vn", retroglu_token_vnormal ) \
   f( "f", retroglu_token_face ) \
   f( "usemtl", retroglu_token_usemtl ) \
   f( "newmtl", retroglu_token_newmtl ) \
   f( "mtllib", retroglu_token_mtllib ) \
   f( "Kd", retroglu_token_kd ) \
   f( "Ka", retroglu_token_ka ) \
   f( "Ks", retroglu_token_ks ) \
   f( "Ke", retroglu_token_ks ) \
   f( "Ns", retroglu_token_ns )

Table of OBJ file tokens understood by the parser.

◆ retroglu_parser_state

#define retroglu_parser_state	(		parser,
			new_state )

Value:

   debug_printf( \
      RETROGLU_TRACE_LVL, "changing parser to state: %d", new_state ); \
   (parser)->state = new_state;

Change the parser state.

Parameters

Pointer	to the RETROGLU_PARSER to modify.
new_state	RetroGLU OBJ Parser States to set the parser to.

Function Documentation

◆ retroglu_parse_init()

void retroglu_parse_init	(	struct RETROGLU_PARSER *	parser,
		struct RETROGLU_OBJ *	obj,
		retroglu_mtl_cb	load_mtl,
		void *	load_mtl_data )

Initialize a RETROGLU_PARSER.

Warning: This should be run before retroglu_parse_obj_c() is called on the parser!

◆ retroglu_parse_obj_c()

MERROR_RETVAL retroglu_parse_obj_c	(	struct RETROGLU_PARSER *	parser,
		unsigned char	c )

Parse OBJ data into a parser, one character at a time.

Generally, this should loop over a character array loaded from an OBJ file.
