💖 V3D 💖

okay bestie, so this is a page from the Allegro manual, section 3alleg4, and it's all about a lil struct called V3D — a fixed point vertex structure that the 3d functions use. it's part of the Allegro game programming library, and honestly? it's giving foundational. 👑

✨ NAME ✨

V3D — the fixed point vertex structure that the 3d functions are obsessed with. Allegro game programming library, periodt. 🦋

🌸 SYNOPSIS 🌸

#include <allegro.h>

typedef struct V3D

🎀 DESCRIPTION 🎀

so the struct is laid out like this, no cap:

   fixed x, y, z;       - position
   fixed u, v;          - texture map coordinates
   int c;               - color

like… x, y, z are all fixed and they hold the position ✨. then u and v are also fixed and they're the texture map coordinates 🧚. and c is an int and it's the color 🌈. that's the whole vibe.

it's a vertex structure used by polygon3d and all the other polygon rendering functions — the way that every polygon renderer is literally pulling up to this struct 😭💅.

🫶 heads up bestie: if you wanna know how to actually obtain or use this structure, go read the description of polygon3d(). that's where the lore lives.

👑 SEE ALSO 👑

and that's the whole page, bestie!! this was pulled from Allegro version 4.4.3 💖 mwah, go render some polygons, you absolute icon. 🎀✨🦋
