A phase-space plot of height v. exaggeration for two different types of balls with two different coefficients of restitution. Nothing important here, just a fun looking plot.
Slippy slidy particles
A friend of mine asked me a question about the way that standing waves make sand on a 2D plate make pretty patterns. So, I whipped up a quick 1D example in Mathematica. I threw 50 randomly distributed… Read More
Recurrence, heat maps, trajectories and fixations
More analysis from Dave Jacobs’ eye tracking project. We wrote all the analysis code ourselves in Mathematica. There’s a bug in the heat map compositing, but I shall procrastinate a solution soon. Lifted largely from Eye Tracking: A comprehensive… Read More
Recurrence plot
Eye tracking recurrence ala Anderson et al. 2013. With Dave Jacobs and the amazing Yarbus and Babcock software packages.
