"Form Constant was inspired primarily by the fluid motions of dance, but also out of a strong desire to collaborate across disciplines and experiment with technologies like real-time motion tracking and general purpose GPU programming. To create the visuals, we tied together a CUDA-based fluid solver to some motion tracking code that captured the position and speed of the dancer from a camera. The GPU fluid simulation code was adapted from the CUDA SDK fluid demo code samples NVIDIA has made available online. Additions and changes to the code for this performance included adding collisions and velocity generation from the dancer. The online GPU Gems series was an enormously helpful resource in understanding the theory behind what we wished to achieve.... We have bigger ideas for future pieces, so we hope to keep developing and collaborating together to create more interesting performances. CUDA has been a blast to learn."
