NAME

       POLYTYPE_GRGB - Polygon rendering mode type Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       #define POLYTYPE_GRGB

DESCRIPTION

       A  gouraud  shaded  polygon which interpolates RGB triplets rather than a single color. In
       256-color modes this uses the global rgb_map table to  convert  the  result  to  an  8-bit
       paletted  color,  so it must only be used after you have set up the RGB mapping table! The
       colors for each vertex are taken from the `c' value, which is interpreted as a 24-bit  RGB
       triplet (0xFF0000 is red, 0x00FF00 is green, and 0x0000FF is blue).
