WebGL path tracer back

Hi guys,

take a look a this WebGL code I found (called "Shiny Toy"). It combines path tracing with ray marching. You can update the code and look at the results. Which advantages have the ray marching? [SMILEY :?:]

Ray marching is merely another kind of intersection method, usually used for different kinds of volumetric functions and data, for example distance field iso-surfaces, smoke etc.

Cool, and it gets even better after about 1000 seconds when the floating point precision starts to be insufficient [SMILEY :D]

See, for example, this tidbit from Inigo Quilez: [LINK http://iquilezles.org/www/material/nvscene2008/rwwtt.pdf]

Ok, I see. So for triangles is better to use raytracing. However,the Inigo Quilez results are very cool!
