ofxOpenCL for openFrameworks 1M Particle Demo on Vimeo

NOTE: The Vimeo compression destroys most of the particles, so I suggest downloading the quicktime from the bottom right.
——————–
This is a demo of an OpenCL particle system based on Rui’s original example at vimeo.com/7298380.

This is 1,000,000 particles being interacted on by mouse, updated on GPU via an OpenCL kernel, data output straight to VBO and rendered without ever coming back to host.

Frame-rate is around 100-200fps running on macbook pro with GF9600GT. (No particle-particle interaction on this one).

Written using ofxOpenCL addon for openframeworks, C++ (though most of the critical stuff is just OpenCL).
