Ray Tracing & Photon Mapping (Unity3D C#)

An article by mgear

Converting some ray tracing code from java/processing (original source by Grant Schindler/2007)

1st version works fine already, just missing the user interactions.. (and its quite slow at the moment)

Current progress: v1.0
– 512×512 render: time 23.65258s (got it down to 16.54801s, if disable preview while rendering..)
– 128×128 render: 1.34s
– Didnt manage to make it faster with small changes, giving up for now.
– Its quite fast in low resolution..
– Here is more interesting project, too bad no sources to download? http://forum.unity3d.com/threads/27612-Real-time-global-illumination
