Wow, that effects.zip patch is simple yet quite nice. I had some fun with that.
One possibility for using combinations of Gem, PDP, and Gridflow together is to use Syphon. It unfortunately only Mac OS X because only that OS currently let's you easily access the graphics card like that. But basically it lets you share data between apps while keeping it on the GPU, so its very fast. Its all open source, there is a syphonserver for Gem. So Gem would need a syphon client, then PDP and Gridflow would need a syphon client and server. I'm sure vade would be responsive to questions if anyone took this on. .hc On Nov 1, 2011, at 5:59 PM, ALAN BROOKER wrote: > > Hi Ricardo, > > > I hop around from these libraries and have used all in performances at > various times ...they’re all great, enthusiastic about all of them, below are > just some of my opinions. > > > PDP/PiDiP is mainly geared towards video and has some really interesting > effects worth checking out- I think performance wise PDP is very efficient > and responsive.
