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.
