Can anyone running a linux and win32 box try to run this example and see if it completely drains you
of CPU. I have tried it with 3 macs and I can't seem to do much more in PD. Also does anyone know
of a less cpu intensive way to track objects in PD using a mac like pix_multiblob does. I would like to
track at least 20 objects. My project is dead unless I figure out a better way.
Thanks,
Alain
