Hi,
is it possible to pass data inside a pfChannel Draw function back to the
application.
Data to the Draw fuction is passed using allocChanData or setChanData.
My fuction doeas the usual pfClear, pfDraw but then get some data using
GL functions,
which I would like to send back. Just by writting into the structure
passed as setChanData
did not work. The man says that inside a pfChannel Draw functin no data
can be passed
upstream (to the app) only Donwstream is done (fro app to draw).
Is there any other way sending data from the pfChannel Draw function
Back?

Thanks
Dimi
