i thought that you should integrate your openCV objects into Gem and not brew your own objects.

I too would like to make some objects in Gem. I have already done some openGL externals for max/msp (see lifeGL and lifeTorus at http://www.billvorn.concordia.ca/menuall.html) and would like to port them to pd. It seems the alternatives are to set a tcl/tk drawable as openGL, or Gem. Is there any documentation about the Gem API or is it all in the Gem source?
