Changer l'angle de la cubemap par rapport au la camera.

Quand on change la position de la camera (or du centre du monde), la cubemap est bien glitcher a cause que les rayons ne pointe pas au bon endroit sur la texture du cubemap

The issue identifies a cubemap glitch when the camera position or world center changes, but names no source file, test, or entry point. Start by reproducing that camera-movement case in the raytracer and trace how cubemap rays are generated; done means the cubemap remains correctly aligned after those position changes.
