More Improvements

Well, my reflection methods for the raytracer aren't working yet. I can make planes now, though.Therefore, everything is going as planned. Cubes shall just have to wait for next week. (Wait... I planned something?)

Anyways, I think I'm doing well: here's some more spheres (still blue!) with a checkered plane.

The shading's fixed, too.

As for class, we learned For loops today. It's interesting that we were taught them first, though... While loops seem simpler. Maybe it's because For loops are more efficient (or so I have heard). Why, though?
