Glaven Object Files

Glaven 13

I’ve posted the Glaven STL and OBJ object files in the Software, Data & Geometry section. Go have a look and let me know if you use them or even download them for that matter.

Specularity and Shape from Line Drawings

My eyes!

OK, just sort of messing around while making some stimuli for this experiment. I’m as creeped out as you are. I promise.

Gießen and the Virgin

Some early experiment data with the Veiled Virgin. I could explain it, but it would give away the study before we even started. So, you’ll have to just do your best to figure out what is going on for now…. Read More

Whatcha lookin’ at?

Some data from Emerson, Max + My summer work. Heat map, where one person looked while making shape discrimination decisions. I think I’ll take a vacation now.      

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

Abby Normal

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

Vision Science 2014 poster

Here’s Phillips, Mazzarella & Docter (2014) for VSS. Get the PDF here Phillips2014 (Draft of 13 May). Specularity and shape from line drawings. If you’re in Florida next week drop in and say ‘hi’. Or not. An interesting thought: this could… Read More
