struct	RETROGLU_VERTEX

struct	RETROGLU_VTEXTURE

struct	RETROGLU_MATERIAL

struct	RETROGLU_FACE

struct	RETROGLU_OBJ

struct	RETROGLU_SPRITE_PARMS
	If draw lists are disabled, this struct holds a list of params for retroglu_set_sprite_clip() so that the sprite can be drawn without a list. More...

struct	RETROGLU_SPRITE

struct	RETROGLU_TILE

struct	RETROGLU_PROJ_ARGS

struct	RETROGLU_PARSER
	As retroglu_parse_obj_c() parses OBJ data, it populates this struct with object information. More...

Typedefs
typedef float	RETROGLU_COLOR[4]

typedef int(*	retroglu_mtl_cb) (const char filename, struct RETROGLU_PARSER parser, void *data)
	Callback to execute when its associate in RETROGLU_OBJ_TOKENS is found in an OBJ file.

typedef int(*	retroglu_token_cb) (struct RETROGLU_PARSER *parser)

Functions
void	retroglu_init_scene (uint8_t flags)

void	retroglu_init_projection (struct RETROGLU_PROJ_ARGS *args)

MERROR_RETVAL	retroglu_parse_obj_file (const char filename, struct RETROGLU_PARSER parser, struct RETROGLU_OBJ *obj)

void	retroglu_draw_poly (struct RETROGLU_OBJ *obj)

void	retroglu_set_tile_clip (struct RETROGLU_TILE *tile, uint32_t px, uint32_t py, uint32_t pw, uint32_t ph, uint8_t flags)

void	retroglu_set_sprite_clip (struct RETROGLU_SPRITE *sprite, uint32_t front_px, uint32_t front_py, uint32_t back_px, uint32_t back_py, uint32_t pw, uint32_t ph, uint8_t flags)

void	retroglu_init_sprite_vertices (struct RETROGLU_SPRITE *sprite)
	Setup the sprite vertices for the poly the sprite will be drawn on. This should be called once when the sprite is initialized, but calling it again later shouldn't hurt.

void	retroglu_init_sprite_vertices_scale (struct RETROGLU_SPRITE *sprite, float scale)

void	retroglu_set_sprite_pos (struct RETROGLU_SPRITE *sprite, uint32_t px, uint32_t py)

void	retroglu_tsrot_sprite (struct RETROGLU_SPRITE *sprite)

void	retroglu_draw_sprite (struct RETROGLU_SPRITE *sprite)
	Draw the given sprite. This function never uses a list, and can therefore be used to create a draw list.

void	retroglu_prerender_sprite (struct RETROGLU_SPRITE *sprite, int list_idx, uint32_t front_px, uint32_t front_py, uint32_t back_px, uint32_t back_py, uint32_t pw, uint32_t ph, uint8_t flags)
	If lists are enabled, prerender the sprite to a list using the given params to retroglu_set_sprite_clip().

void	retroglu_jitrender_sprite (struct RETROGLU_SPRITE *sprite, int list_idx)
	If lists are enabled, render the sprite list at list_idx. Otherwise, draw the sprite using retroglu_draw_sprite().

void	retroglu_free_sprite (struct RETROGLU_SPRITE *sprite)

MERROR_RETVAL	retroglu_init_glyph_tex ()
