Installing PDP & PiDiP did not lead to a big success either because of a knowledge-lack on my side as well as few documentation and poor performance on OSX. http://iem.kug.ac.at/mailinglists/pd-list/2003-10/006710.html The links in this suggestion are broken.
yep, this mail precisely explains that PoDoP is now included in PDP and that it doesn't exist by itself anymore.
video tracking on 0SX would not work because the camera input is not handled ( yet ) in OSX, it works perfectly well on linux ( objects pdp_shape, pdp_ctrack ).
the doc, well, it's the help patches...
cheers, sevy
