EyeWriter

From the EyeWriter website:
“Members of Free Art and Technology (FAT), OpenFrameworks, the Graffiti Research Lab, and The Ebeling Group communities have teamed-up with a legendary LA graffiti writer, publisher and activist, named Tony Quan, aka TEMPTONE. Tony was diagnosed with ALS in 2003, a disease which has left him almost completely physically paralyzed… except for his eyes. This international team is working together to create a low-cost, open source eye-tracking system that will allow ALS patients to draw using just their eyes. The long-term goal is to create a professional/social network of software developers, hardware hackers, urban projection artists and ALS patients from around the world who are using local materials and open source research to creatively connect and make eye art.”

One million particles in OpenCL + OpenFrameworks

Memo Akten took my OpenCL particle example and removed the particle to particle interaction (it’s a frame rate killer) and optimized it to run in the gpu. The result is one million particles interacting with the mouse running at over 100 frames per second!!!!

OpenCL Particles test

a test using OpenCL andOpenFrameworks.
5000 particles interact with each other and mouse cursor.
this runs easily at 30fps but snapz killed the framerate a little

this is running only on cpu and letting OpenCL do its thing. Its a lot faster than simply running it with “normal” code, but it definitely could run much faster on gpu.

source for this can be downloaded here: code.google.com/p/ruisource/
it includes a slightly modified version of the ofxOpenCL addon by Memo Akten.
