A 3D engine made completely from scratch
using only OpenGL
It's re-starting cuz I moved from SDL to OpenGL
Those meshes were made manually, so this bottle
is more amazing than the whole code
I changed the normal projection matrix for a vector because
it seems to be faster and cleaner (maybe idk)
Since I'm using .obj
files now, I'll let the bottle live here
