The sqrt() of all evil...

I've been working on some 3D stuff for ProjectLCD. It's obvious that I've been pampered by working with OpenGL on PC for a while now, because I seem to have forgotten a whole lot of vector math.
Anyway, J2ME doesn't have any sqrt() function, so I had to research a bit on how to implement it, and boy does it take a lot of instructions to calculate. The performance on slower device will probably take a hit, but it shouldn't be too bad since I only need one sqrt() per triangle.

In other news, I've started thinking about a redesign of my website which is long overdue. I found some nice templates to use as a base, but we'll see when I get around to actually doing something.
