Hi,
I am new to pd, i have been using max/msp and jitter. I am now considering changing to pd.
But I have one question: In max I used webcams to collect data and transformed this to sound or/and to different variables which controlled the playback of soundfiles. Can this be done in pd?
If yes, then how? What do I need?
Thank you!

Depends exactly on what you want to do, but your best bet is to check out the GEM library for pd, this allows you to hook up webcams etc and there are some examples of video analysis in the help files, including a motion tracking example, this is probably the example of most use to you as it shows basic examples of tracking light levels etc, this data can obviously then be used to control whatever sound sources or sythesis parameters you wish. For interactive stuff pd has some conditional switchs such as [spigot] [route] and [select] that are useful for making game logic.

Hope this is useful, post a more specific question if you want anymore info

good luck

Thanks that is most useful! Motion tracking stuff what I needed the most! I will check it out.
