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.

NAME

       ex3d - 3d 'bouncy cubes' demo. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       Example ex3d

DESCRIPTION

       This  program  demonstrates  how  to use the 3d matrix functions.  It isn't a very elegant or efficient piece of code, but it does show the
       stuff in action. It is left to the reader as an exercise to design a proper model structure and rendering pipeline: after all, the best way
       to do that sort of stuff varies hugely from one game to another.

       The  example  first  shows a screen resolution selection dialog.  Then, a number of bouncing 3d cubes are animated. Pressing a key modifies
       the rendering of the cubes, which can be wireframe, the more complex transparent perspective  correct  texture  mapped  version,  and  many
       other.
