POLYTYPE_ATEX(3)		Allegro manual		      POLYTYPE_ATEX(3)

NAME
       POLYTYPE_ATEX  -	 Polygon  rendering mode type Allegro game programming
       library.

SYNOPSIS
       #include <allegro.h>

       #define POLYTYPE_ATEX

DESCRIPTION
       An affine texture mapped polygon. This stretches the texture across the
       polygon	with  a	 simple 2d linear interpolation, which is fast but not
       mathematically correct. It can look OK if the polygon is	 fairly	 small
       or  flat-on to the camera, but because it doesn't deal with perspective
       foreshortening, it can produce strange warping artifacts. To  see  what
       this  means,  run  Allegro's  test  program and see what happens to the
       polygon3d() test when you zoom in very close to the cube.
