💖 qscale_matrix(3) 💖

okay so bestie, this page is from the Allegro manual and it's literally about two functions that are so iconic for matrix scaling. let's get into it ✨

🌸 NAME 🌸

qscale_matrix, qscale_matrix_f — optimised routine for scaling an already generated matrix. this is part of the Allegro game programming library 🎮

✨ SYNOPSIS ✨

#include <allegro.h>

void qscale_matrix(MATRIX *m, fixed scale);

void qscale_matrix_f(MATRIX_f *m, float scale);

🎀 DESCRIPTION 🎀

okay so listen, this is the optimised routine for scaling an already generated matrix. the way it works is it simply adds in the scale factor, so there is no need to build two temporary matrices and then multiply them together. like, it's giving efficiency, no cap. 💅✨
