NAME

       POLYTYPE_PTEX - Polygon rendering mode type Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       #define POLYTYPE_PTEX

DESCRIPTION

       A  perspective-correct  texture mapped polygon. This uses the `z' value from the vertex structure as well
       as the u/v coordinates, so textures are displayed correctly regardless of the angle they are viewed from.
       Because  it  involves  division calculations in the inner texture mapping loop, this mode is a lot slower
       than POLYTYPE_ATEX, and it uses floating point so it will be very slow on anything less  than  a  Pentium
       (even  with  an  FPU,  a 486 can't overlap floating point division with other integer operations like the
       Pentium can).
