POLYTYPE_GRGB(3alleg4)

💖 NAME 💖

POLYTYPE_GRGB — bestie, it's a polygon rendering mode type from the Allegro game programming library 🎀

✨ SYNOPSIS ✨

#include <allegro.h>

#define POLYTYPE_GRGB

🦋 DESCRIPTION 🦋

Okay so listen. POLYTYPE_GRGB is a gouraud shaded polygon, but not like the regular kind — instead of interpolating one single color across the whole thing, it interpolates RGB triplets. Full color gradient vibes, it's giving sunset energy fr fr 🌅

⚠️ In 256-color modes this uses the global rgb_map table to convert the result into an 8-bit paletted color, which means it must only be used after you have set up the RGB mapping table! No cap, if you skip that step you're gonna have a bad time 😭

The colors for each vertex come from the c value, and that value gets interpreted as a 24-bit RGB triplet. So like:

• 0xFF0000 is red 🔴
• 0x00FF00 is green 🟢
• 0x0000FF is blue 🔵

That's it, that's the whole color language. Slay 💅
