get_trans...ion_matrix(3alleg4)

💖 get_transformation_matrix 💖

ok so bestie, this one's from the Allegro manual (the game programming library, you know the vibe 🎮✨), and it's genuinely one of those functions that makes 3D stuff go brrr. Let me put you on.

✨ NAME ✨

get_transformation_matrix — constructs X, Y, Z rotation matrices with an angle and scaling. it's giving Allegro game programming library energy fr fr 🦋

🌸 SYNOPSIS 🌸

#include <allegro.h>

void get_transformation_matrix(MATRIX *m, fixed scale, fixed xrot, yrot,
zrot, x, y, z);

🎀 DESCRIPTION 🎀

okay so here's the tea ☕ — this function builds you a transformation matrix, and that matrix is about to do three things to your points, in order, no skipping:

• rotate them around all three axes by the amounts you pass in (and heads up, those angles are in binary, 256 degrees to a circle format — not your regular degrees, bestie, don't get caught slipping 😭)
• scale the result by the amount you specify — and listen, if you want no change of scale, you pass 1. that's it. 1. periodt 💅
• then translate to the x, y, z position you asked for

so it's rotate → scale → translate, and you get one shiny MATRIX out of it. iconic behavior honestly 👑

this was brought to you by Allegro version 4.4.3 — yeah she's been around a minute but she still slays, okurrr 💖✨🌈 go make something cute in 3D for me, mwah 🎀
