POLYTYPE_ATEX(3alleg4) Allegro manual POLYTYPE_ATEX(3alleg4)
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 per-
spective 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.
