Lissajous and lava lamps

  • 12 June 2009

Time for another demo video. This time I’ve tried to create a 2D function on a 3D surface by playing around with the colours of some function.

In the 90s I used to love watching clever computer demos. One of the visual effects that was sometimes used was that of viscous circles or spheres that would meld together when they moved close one another. This created the kind of effect you get with a lava lamp. In this demo I try to recreate this effect using a couple of functions and a computer that’s probably several thousand times more powerful than the ones the demos ran on. Does the resulting effect work? See for yourself!

I do apologise though for the terrible delivery.
