Particle trails

Messing around with feedback to get flow lines from the fluid sim. The color represents velocity direction and value is the magnitude of the velocity. Particles can bounce around obstacles and don't spawn inside them. 1 million particles @60 fps.

GPU particles

Here's 250,000 particles being advected by the velocity field. This is being done using glsl shaders in TouchDesigner. The value of the particles is currently just the magnitude of the velocity, but I'll be adding a lot more color options later. I'm maintaining 60fps using a 512x512 fluid container.

I'm going to spend the next couple of weeks making big pushes in UI to prepare for a public demonstration at the end of year show. A lot to do still.
