A day of problem solving pictures.

One of the things I love about using Mathematica is that it helps me better understand the nature of my programming and problem solving. It’s a great tool to help make sense of problems, see your errors, verify… Read More

More good bad results

Some days, things don’t go well, but you end up with interesting looking things anyway.

Very preliminary, for Eric. [WolframCDF source=”http://flipphillips.com/wp-content/uploads/2014/06/Glerp.cdf” width=”433″ height=”520″ altimage=”http://flipphillips.com/wp-content/uploads/2014/06/Glerp.png” altimagewidth=”433″ altimageheight=”520″]  

When I do the wrong thing…

It eventually looks like this, which is the ‘right thing’ [WolframCDF source=”http://flipphillips.com/wp-content/uploads/2014/06/notwtf.cdf”… Read More

Pegged. It will come back to you?

Doing a sort of gigantic parallel computation in Mathematica. A little too gigantic, I’m afraid. Um- can IT deliver my new MacPro sooooon? Pleeeeease?

I was trying to figure out why there were shading artifacts on a 3D object I created for some vision experiments. I’ve got a metric-ton of Mathematica I’ve written over the years for doing computational geometry and it stood… Read More


Back in 1987 I wrote some code for generating ‘noisy objects’. I cleaned up that code over the years, enhanced some calculations, played with new Mathematica features. Now I’ve got stuff that looks like this. I’ll put a… Read More

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

Sculpted Golden Boy

A stimulus, # 13, otherwise known as ‘golden boy’ Colors indicate mapping of under- and over-sculpt from a shape production experiment where we had artists and non-artists reproduce shapes using only vision, touch, or some combination of both… Read More

Anticipation of Sabre Fencing Attacks

A set of motion-capture trajectories for the Anticipation of Sabre Fencing Attacks paper by Pete Possidente and I.   You can see the ‘whip’ of the tip of the sabre at the end of the attack (green dots on… Read More
