Kineme CVTools, v0.3
I haven’t really checked except my personal setup, OS X 10.6.8 and Quartz Composer 4.0.
Hopefully it will work with other configuration too.
Last winter, I was into edge detection and particle effect. I tried to make something legitimate with Quartz Composer. This is the result of my struggle. So far I played with this patch only once in public as part of opening visual set for Richie Hawtin’s 6 hours of DJ show at Time Warp Mannheim on last March. I just thought I would be able to arrange and share it before I forget everything.
