scene_polygon3d(3)		Allegro	manual		    scene_polygon3d(3)

NAME
       scene_polygon3d,	 scene_polygon3d_f  - Puts a polygon in	the scene ren-
       dering list. Allegro game programming library.

SYNOPSIS
       #include	<allegro.h>

       int scene_polygon3d(int type, BITMAP *texture, int vc, V3D *vtx[]);

       int scene_polygon3d_f(int type, BITMAP *texture,	int vc,	V3D_f *vtx[]);

DESCRIPTION
       Puts a polygon in the rendering list. Nothing  is  really  rendered  at
       this moment. Should be called between clear_scene() and render_scene().

       Arguments  are  the same	as for polygon3d(), except the bitmap is miss-
       ing.  The one passed to clear_scene() will be used.

       Unlike polygon3d(), the polygon may be  concave	or  self-intersecting.
       Shapes  that penetrate one another may look OK, but they	are not	really
       handled by this code.

       Note that the texture is	stored as a pointer only, and you should  keep
       the actual bitmap around	until render_scene(), where it is used.

       Since  the  FLAT	 style is implemented with the low-level hline() func-
       tion, the FLAT style is subject to  DRAW_MODEs.	All  these  modes  are
       valid. Along with the polygon, this mode	will be	stored for the render-
       ing moment,  and	 also  all  the	 other	related	 variables  (color_map
       pointer,	pattern	pointer, anchor, blender values).

       The settings of the CPU_MMX and CPU_3DNOW flags of the cpu_capabilities
       global variable on entry	in this	routine	affect the choice of low-level
       asm routine that	will be	used by	render_scene() for this	polygon.

RETURN VALUE
       Returns	zero  on success, or a negative	number if it won't be rendered
       for lack	of a rendering routine.
