render_scene(3alleg4)						  Allegro manual					     render_scene(3alleg4)

NAME

       render_scene - Renders all the queued scene polygons. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       void render_scene();

DESCRIPTION

       Renders	all  the  specified  scene_polygon3d()'s  on the bitmap passed to clear_scene(). Rendering is done one scanline at a time, with no
       pixel being processed more than once.

       Note that between clear_scene() and render_scene() you shouldn't change the clip rectangle of the destination bitmap.  For  speed  reasons,
       you should set the clip rectangle to the minimum.

       Note also that all the textures passed to scene_polygon3d() are stored as pointers only and actually used in render_scene().

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.
