on osx and linux you can use [pix_share_read] and [pix_share_write] to share images between two instances of Pd/Gem on one(!) computer via shared-memory. this should be very fast. afair, there are some freeframe-plugins that allow you to send images from one host to another (via network), but i don't know on which platform they are available (i guess: w32) and whether they are free; i never tried them, but they should be usable with [pix_freeframe]. depending on what you are doing, it might be easiest to just run 2 (synched) instances of Gem that independently produce the 2 visuals (and are controlled by a single patch) or use a multi-monitor setup and do clever things to get 2 virtual monitors in a single gemwindow. or pay the developers a lot of money to finally get the multi-window support into Gem which i have been promising for more than 3 years :-) fgamdsr IOhannes _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
