In the future, you’ll just download the STL and fix it yourself

Well, not quite. Back when I started doing 3D printing (around 2002 or so, very expensive, very cool) one piece of sales hype was – Soon, when your dishwasher breaks, you’ll just buy the STL for the part… Read More

Creating noisy stimuli

So much noise. A method for creating a variety of pseudo-random `noisy’ stimuli that possess several useful statistical and phenomenal features for psychophysical experimentation is outlined. These stimuli are derived from a pseudo-periodic function known as multidimensional noise…. Read More

Perceptual representation of visible surfaces

What is a surface, anyway? Two experiments are reported in which we examined the ability of observers to identify landmarks on surfaces from different vantage points. In Experiment 1, observers were asked to mark the local maxima and… Read More

Implicit madness

A sparse implicit surface. It needs to be less sparse.

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.

Gibson ‘Feelie’ Object Files

I’ve created a OBJ and STL repository of printable / renderable versions of Gibson’s ‘feelies’ haptic dataset. Go have a look and let me know if you download and/or use them.

More good bad results

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

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
