Re: Opencv examples missing parts

the plugin needs to go into the ~/library/graphics/patches folder. if it is all ready in this folder that check your root graphics folder as you may have a duplicate that is causing problems. more than likely its in the wrong folder as this is a kineme plug which uses the unofficial api and belongs in the patches folder not plugins folder

I find that the KinemeCore plugin helper is a real time saver - just right mouse click [Control + click] the plugin to be installed - send it to the KinemeCore plugin handler and voila - it's installed - sweet :-)

Also our OpenCV plugin is 32bit-only currently, so if you're using Snow Leopard, you'll need to open Quartz Composer in 32bit mode.

Thanks guys, that did the trick, pretty neat stuff. So in essence could i use opencv to track someones hand with pretty particles ?
