scene_polygon3d(3)              Allegro manual              scene_polygon3d(3)



NAME
       scene_polygon3d, scene_polygon3d_f - Puts a polygon in the scene
       rendering 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
       missing.  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()
       function, the FLAT style is subject to DRAW_MODEs. All these modes are
       valid. Along with the polygon, this mode will be stored for the
       rendering 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.
