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.
Omega-style headphone stand
For my birthday I bought myself a nice set of headphones — Grado PS500. They were sitting on my desk, in a pile of coffee stained Natures and strange SkidShop snack-bags.
So I designed and printed the following, inspired by the so-called “Omega” headphone stands that are out there. Check it out at Thingaverse
Oh and a shout-out to McNeel and Assoc for letting me be part of the Rhino for Macintosh beta-group.
Wolfram Programming Cloud
You can create this:
[WolframCloudAPI id=”a99541cf-90ab-4b52-ab5c-cd6b632f4c7f” rule=”62″ step=”30″]With this:
[wlcode] CloudDeploy[APIFunction[{“rule” -> Restricted[“Number”, {0, 255, 1}] -> 30,
“step” -> Restricted[“Number”, {0, Infinity, 1}] -> 50
},
ArrayPlot[CellularAutomaton[#rule, {{1}, 0}, #step],
Frame -> False] &,
“PNG”
], Permissions -> “Public”] [/wlcode]
Fun! Check out some of the fun stuff here https://www.wolframcloud.com
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 and validate your computations.
Here is a set of 26 images from today’s efforts to solve a particular problem of differential geometry on densely sampled meshes.

Very preliminary, for Eric.

When I do the wrong thing…
It eventually looks like this, which is the ‘right thing’

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 me in good stead. The blue ‘V’s you see are mismatched surface normals – they should be coincident (e.g. exactly the same) but, as you can see, there is a systematic error. Fixed it.
