\"\"<\/a><\/p>\n

Converting some ray tracing code from java\/processing (original source by Grant Schindler\/2007)<\/p>\n

1st version works fine already, just missing the user interactions.. (and its quite slow at the moment)<\/p>\n

Current progress: v1.0<\/strong>
\n– 512×512 render:\u00a0 time 23.65258s (got it down to 16.54801s, if disable preview while rendering..)
\n– 128×128 render: 1.34s
\n– Didnt manage to make it faster with small changes, giving up for now.
\n– Its quite fast in low resolution..
\n– Here is more interesting project, too bad no sources to download? http:\/\/forum.unity3d.com\/threads\/27612-Real-time-global-illumination<\/a><\/p>\n
