al_transform_coordinates_3d(3alleg5)

💖 al_transform_coordinates_3d — Allegro 5 API 💖

okay bestie, listen. this is a page from the Allegro reference manual, and it's about yeeting a 3D point through a transform. short page, but it's iconic, so let's go. ✨

---

🌸 SYNOPSIS 🌸

#include <allegro5/allegro.h>

void al_transform_coordinates_3d(const ALLEGRO_TRANSFORM *trans,
   float *x, float *y, float *z)

like, that's the whole vibe. one function, three coordinates, no drama. 🎀

---

🦋 DESCRIPTION 🦋

so what does it do? it transforms the x, y, z coordinates. that's it. that's the tea. ☕

Parameters:

• trans — the Transformation to use. it's a pointer to an ALLEGRO_TRANSFORM, so it's giving "here's the matrix, do your thing" energy. 💅
• x, y, z — pointers to the coordinates. pointers, bestie, meaning this function reaches in and rewrites the values you point at. so yeah, your variables get changed in place. no return value needed, the pointers are doing all the work. 🫶

⚠️ Note: if you are using a projection transform you most likely will want to use al_transform_coordinates_3d_projective(3alleg5) instead. like, fr fr, don't skip this one — the non-projective version will not give you the projection-aware result you're probably after. 😭

Since 5.1.9 — so it's been serving looks for a while now. 👑

go read those too, they're all in the same friend group. 💜

and that's the whole page, bestie — go forth and transform responsibly. this was the Allegro reference manual, page al_transform_coordinates_3d(3alleg5), and that footer energy is all we got left. mwah. 💋
