ok so bestie, this is a page from the Allegro manual, and it's all about viewing a 3d world from an arbitrary camera position β¨ lowkey iconic tbh
β¨ NAME β¨
excamera β viewing a 3d world from an arbitrary camera position. It's part of the Allegro game programming library π
πΈ SYNOPSIS πΈ
#include <allegro.h>
Example excamera
like. that's it. that's the whole synopsis. she's minimal, she's demure π«Ά
π¦ DESCRIPTION π¦
okay so here's the vibe: this program is literally a demonstration β a lil showcase β of how you use the get_camera_matrix() function to view a 3d world from any position and angle. any. periodt π
The example draws a checkered floor through a viewport region on the screen, which ngl is giving very much "graphics demo from a magazine cover disc" and I am obsessed ππ
You can use the keyboard to:
- move around the camera π₯
- modify the size of the viewport π
and the keys that can be used with this example are displayed between brackets at the top of the screen β so if you ever forget what does what, just look up bestie, it's right there β¨
no cap, the on-screen key list is the whole tutorial. read the brackets. the brackets are your friend π«Ά
