Recently I had the opportunity to speak at the Berlin TouchDesigner Summit, hosted by Derivative, makers of TouchDesigner.

I gave a talk on using TouchDesigner and GLSL to make a fluid simulation using the Navier-Stokes noncompressible fluid advection formulae, and I lead a workshop on drawing in python for plotters like the AxiDraw. Both those videos are online now.

The workshop is a bit long and didn't move as fast as I'd liked - it was billed as an intermediate workshop but the crowd was of a mixed skill level so we paused a lot for bug hunts ... in retrospect I should have made the step by step instructions a little more clear.

In contrast, the GLSL talk moves at 100mph the whole time, so you don't need to watch in fast-forward.

Enjoy!

A basic fluid system will serve as an entree to discuss render buffers, pixel formats, texture buffers, and GLSL best practices in the TouchDesigner context.

Additional Files - https://github.com/ancillarymagnet/axidrawings This workshop will focus on the basics of using TouchDesigner's Script SOP to create geometry programmatically, beginning simply with the creation of points and lines, building out some useful and reusable abstractions, and eventually creating interesting structures and patterns, all with an eye to creating vector artwork for printing on pen plotters like the Axidraw or Makeblock.
