Re: [PD] Gem: sharing a framebuffer among instances of Pd
pix_share only does pix_ images in RAM. You mention gemframebuffer which is a buffer on the GPU, and there is no way to share that between processes.

You mention gemframebuffer which is a buffer on the GPU, and there is no way to share that between processes. It is not possible to manage the PBO and share pixels in the same way than RAM ?

Not without bringing the pixels from the GPU back to RAM first. It would work, but not be efficient. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

I know vade has been working on doing this cross-applications using a new Mac OS X feature called IOSurface. Donno the status of that project. I do know he has it working in QuartzComposer and maybe another app. .hc On Jul 14, 2010, at 2:41 PM, Max wrote: Hi list, i remember vaguely that someone (cyrille? cclepper?) mentioned that it's possible to share a gemframbuffer among multiple instances of Pd to transfer a video stream for example. how is that achieved exactly? thanks, m.___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list The arc of history bends towards justice. - Dr. Martin Luther King, Jr. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
