More ray diagrams

I’ve dug into this ray diagram sketch on CodePen because it’s pretty satisfying to twiddle the properties of the simulation and see how things change. I’ve added some sliders, but beware of the code – it isn’t pretty. I’d say it’s about reached the point of unmaintainability.

The UI is a total wreck, but you can currently alter all the major parameters. There aren’t any measurements yet, which is probably the next most important feature. It’s fine and dandy to move these virtual lenses around and see how the rays refract, but without the proper measurements it’s not actually a useful tool. Also there isn’t a way to change the lens type or order, and once you can do that, you’ll really want to be able to save and load a given configuration.

And this hasn’t even gotten into the optimization part! That’s the whole purpose!
