Audio visualization, obstacle velocity

Here's a quick update that includes a couple new features: passing velocity in with obstacle data and rendering 3d geometry to a 2d image to use as input (although in this video, actual obstacles and density fields aren't present). I've got a simple particle simulation running on the CPU in TouchDesigner whose initial velocity and direction is being controlled by an audio waveform. I followed along with Derivative's 2016 Norway Workshop to get the system set up. Particle velocities are rendered as colors and piped into the CUDA sim. Adding these features went fairly smoothly.

Here it's very apparent that the simulation container doesn't have any interesting border conditions, which can be a good and bad thing. It's another feature to add. In the coming months, I'll be working on the UI, different composition techniques, experimenting with looks, and improving stability to prepare for MAT's End of Year Show. I've also become very interested in Ted's Wavelet Turbulence paper which would really send the visuals through the roof. No timeline on that yet, but it's going on the list.
