excamera(3alleg4)

✨ excamera ✨

okay bestie, welcome to the Allegro manual — this is excamera(3alleg4), and it's giving 3d world, any camera angle you want. no cap. 🎀

💖 NAME 💖

excamera — viewing a 3d world from an arbitrary camera position. it's part of the Allegro game programming library, periodt. 🦋

🌸 SYNOPSIS 🌸

#include <allegro.h>

Example excamera

✨ DESCRIPTION ✨

so this program is literally a whole demo of how to use the get_camera_matrix() function to look at a 3d world from any position and any angle. like, the camera is the main character and you're the director. 👑

it draws a checkered floor through a viewport region on the screen — so you get a lil window-y rectangle of 3d floor instead of the whole screen, and that's the vibe. 🧚

and then you get to play: you can use the keyboard to move around the camera, OR to change the size of that viewport. your call, you're in charge. 💅

the keys that work with this example? they're displayed between brackets at the top of the screen, so you never have to guess. no cap, it just tells you. 🙈
