POLYTYPE_GRGB(3)                Allegro manual                POLYTYPE_GRGB(3)


POLYTYPE_GRGB - Polygon rendering mode type Allegro game programming library.


#include <allegro.h> #define POLYTYPE_GRGB


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).
