Renderer

how can i make a renderer that will generate a circle when a color presents on tha cam shift tracker?!
thanks in advance!!

i dont know, but i am quite sure, that there is a help patch for the cam shift tracker, it will explain all you need. press F1, the magic button…

i have read the help, and i found out how camshift tracker works.
now i will make a renderer beside the one that cam shift tracker has, in which it will be an image projected when a color subject is in front of the camera.
anyone ideas?!
