triangle3d(3alleg4)

💖 triangle3d — Allegro manual 🎀

okay bestie, so this is triangle3d(3alleg4) from the Allegro manual, and it's literally the glow-up your 3d triangle rendering has been waiting for ✨

🌸 NAME 🌸

triangle3d, triangle3d_f — draws a 3d triangle onto the bitmap you picked, no cap. part of the Allegro game programming library, obviously 💅

✨ SYNOPSIS ✨

#include <allegro.h>

void triangle3d(BITMAP *bmp, int type, BITMAP *tex, V3D *v1, *v2, *v3);

void triangle3d_f(BITMAP *bmp, int type, BITMAP *tex, V3D_f *v1, *v2,
*v3);

🦋 DESCRIPTION 🦋

so the whole vibe here is: you're drawing 3d triangles, and you get to choose whether you're doing it with fixed point or floating point vertex structures. pick your fighter 💖

now here's the tea 🫖 — unlike quad3d[_f](), the triangle3d[_f]() functions are not wrappers of polygon3d[_f](). nope, they're doing their own thing. they've got their own routines that take into account the constantness of the gradients. it's giving main character energy, fr fr 👑

and because of that, this:

triangle3d[_f](bmp, type, tex, v1, v2, v3)

is faster than this:

polygon3d[_f](bmp, type, tex, 3, v[])

speed, bestie. we love to see it ⚡

📖 also! go read the beginning of chapter "Polygon rendering" for the full list of rendering types you can use with this function. iykyk, don't skip it 🌈
