NAME

       create_scene - Allocates memory for a 3d scene. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int create_scene(int nedge, int npoly);

DESCRIPTION

       Allocates  memory  for  a scene, `nedge' and `npoly' are your estimates of how many edges and how many polygons you will render (you cannot
       get over the limit specified here). If you use same values in successive calls, the space will be reused (no new malloc()).

       The memory allocated is a little less than 150 * (nedge + npoly) bytes.
