Perlin sphere cutaway from spherical shell

If you don t know what a distance estimator is, you ll find some quick introductions here. Having discussed folding space in some detail, I d like to go over some interesting uses of perlin noise that you can apply to simple distance estimation functions.

Simple reflections along with a full article on how to raytrace them.

So there s quite a lot that I haven t got round to discussing yet including some of the very basic things that take a raytracer from a lone billiard ball simulator to a system capable of rendering many billiards in cool ways.

Specular highlight + diffuse = gloss!

In the last post I talked about the basic principles that allow you to put a raytracer together and I showed the first image that most people get to when building their own. THE SPHERE.

Simple coloured lighting example. More information about how to code this here... http://woo4.me/raytracer/simple-lighting/
