This is a test of my HTML5 demosystem, version 0.4, featuring realtime raymarching (on the GPU) with distance fields (also known as sphere tracing).
This test shows an animation of blended solids with soft shadows and object space ambient occlusion.
The raymarching code is very simple and not optimized. On my ATI 5770 i get about 30 frames per second at 1680 x 1050.
This is the video conversion of the WebGL animation available at: http://postronic.org/h3/test/webgl/ds04/
(requires a browser with WebGL support and a recent video card)
