It's my spiral scene with a plane and triangle. And if you look closely, you can see that the spheres are only reflecting where they are supposed to (the problem was that intersections behind the starting point of any ray with a plane were counted).
I suppose the project's complete.
In class this week, we learned about the pointers behind Java variables. I've heard it mentioned before, but I think I finally understood it: before, I had just used intuition. Finally, something somewhat useful- in the curriculum!
But now, since classwork is all done and I have no raytracer to work on, I have nothing to do. Maybe a 3D raycaster?
Or I could do something without three dimensions, for a change. I wonder...
