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).
