💖 V3D_f — bestie's guide to the floaty lil' vertex 💖

okay so you found yourself a page from the Allegro manual (that's section 3alleg4, iykyk) and it's all about V3D_f — the floating point vertex structure that all the 3d functions in the Allegro game programming library are absolutely obsessed with. it's giving "tiny struct, huge main character energy". ✨

✨ SYNOPSIS ✨

#include <allegro.h>

typedef struct V3D_f

like yes bestie that's the whole synopsis, it's a struct, we move. 🎀

🦋 DESCRIPTION 🦋

okay so here's what's inside this little guy:

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

let me translate, because the way that x, y and z are just the position — like where in space this vertex is vibing — is so real. then u and v are your texture map coordinates (the "which pixel of the texture am I" situation), and c is the color. periodt. 💅

so basically it's exactly like V3D, except — and this is the whole plot twist — it uses float values instead of fixed ones. floats. fancy. 💖

and if you wanna know how to actually obtain and use this structure, the manual is like "go read the description of polygon3d_f()" — so go do that, bestie, it's all in there. 🫶

🌸 SEE ALSO 🌸

the group chat, the whole squad, no one left out:

ngl V3D_f is the float twin of V3D, so if you're mixing them up, vibe check your types before you ship it. 😭

that's the whole page, you ate it, go be iconic with your vertices. 💜 this was Allegro version 4.4.3, dropping the V3D_f(3alleg4) energy, and yeah — that's the sign-off, mwah. 🎀✨🦋
