I decided to give the Cinder library a try based on the packed feature set.
This is a little demo application made with the Kinect that runs about 4000 particles in real time using only the Cinder API drawing methods. I believe Cinder will prove to be about 2x faster than openframeworks across the board, which is awesome.
I’ve hooked up box2d but haven’t had a chance to optimize any of the rendering yet.
[Update]
Still fleshing out the architecture of the Kinect painting program.
