Out of curiosity, how does one enable this second option (2 separate sub windows?)
A good friend of mine and I are working on a project (well, im helping him with some basic stuff..)... for doing 3D video playback from stereoscopic footage shot while skydiving. He has mounted 2 cameras to his helmet and has recorded some footage, and we are looking for easy ways to send frame accurate (read synched) video to two projectors, and will probably end up using polarized filters and glasses to view. We last tested max/jitter using a very large 1600x600 (2 800x600 quicktimes 'glued' together) and using jit.scissors to separate them to two instances of jit.window. Even on a dual G5 2.5 Ghz with 4 Gb ram, we dropped frames using mjpeg codec, but uncompressed video seemed to be ok. I would like very much to use Gem, but since one cant instantiate two windows (on OS X at least..), I thought it might not work... I dont think that G5 ever worked that hard, which to me was very very surprising.
Does anyone have any example patches doing something similar, and keeping proper frame synch from either one, or two pix_movies? I have great faith that Gem and PD will be much smoother.
Thanks much. You guys are all too cool!
These projects sound very interesting..

right now, there are 2 stereo-modes in Gem, anaglyph (e.g. red/green) and one with 2 separate sub-windows (both in one "real" window).
anaglyph renderign is probably not what you want.
Any thoughts would be appreciated!
btw, the multiple_window feature could likely be what you need for a cave-like situation. in theory you could have one instance of Gem on one master-computer, and several slave-renderers (via remote windows) this would (right now) only work under linux and i am pretty sure that you could not deal with large textures. (i once did it with live-video forwarded to 1 single slave, which worked, but never tried several slave-machines (multiple_window did not exist back then)
