GLSL Fractals
Animated Fractals with WebGL & GLSL
These use raycasting to render fractals, with a camera which moves slowly through the scene. Using a very low number of raycasting steps yields some interesting effects. Using a moderate number of steps produces something that looks like blurry fog.
This example uses screen-space lighting (based on z-buffer derivatives) and edge detection for a cartoon rendering effect.
