Modeled in TopMod. Sub-divided in meshlab to save time. For some reason meshlab can sub-divide in less than a second when TopMod takes 5 or more minutes. Rendered in Sunflow.

using mirrors to turn a single kinect into 5 kinects, scanning all sides of an object simultaneously.
you can't really do it in a single frame, you have to move an aperture around in front of the ir projector and build up a depth image. otherwise there is too much interference from the reflections of the projection.
As you can see, things work a lot better than in the previous version. Not all though, so I expect to be doing a third and hopefully final prototype soon.
Sweet: Managed to get the normalmap.gdp shader from MeshLab working in Processing. Crimes against good taste may commence. I'm using Andres Colubri's GLGraphics library to handle the shader. Thanks to Greg Borenstein for his sample code, which is available on GitHub.
Playing with Structure synth yesterday I came across a few quite interesting things.
So far I was using the template exporters to get some renders done in Sunflow or POV ray but both only offer text editors to position cameras and light - no interactive way like Blender.
By the way I don't use Blender because my computer doesn't like it - a Blender render has a 1 in 3 chance to crash my computer - something like dodgy memory ?
So I was looking for other ways and there is quite a nice one.
You can actually paste the complete Eisen script from Structure synth into MeshLab.
Not under open or import but straight under Filters->Create New Mesh Layer is the point 'Structure Synth Mesh creation'
Select the Eisen script and copy it (Ctrl-c) - go to MeshLab to Filters->Create New Mesh Layer ->Structure Synth
This will open up a small input box - click in there - press Ctrl-a to select all and Ctrl-v to paste your script.
I don't change any other values.
This will create the structure in MesLab and you have many different ways to export it from there.
I exported it to a VRML (.wrl) because I wanted to put some lighting in via PoseRay.
So import the wrl file there and setting up lights and materials just became a lot easier than text based in the POV ray editor.
Then I was curious what the 'Kerkythea Output' is. Turns out that Kerkythea ( www.kerkythea.net) is a freeware renderer I have never heard about.
Downloaded it and a few resources like Materials and skies and it looks actually quite OK.
So in PoseRay I exported via the Kerkythea output to Standard XML (the KT zipped XML did not work for me) and imported that one to the Kerkythea renderer.
After playing around for about an hour I found some lights, materials and sky I was happy with and left it for another 3 hours to render with Bidirectional Path tracing.
So long story short here is the result of this totally free way of creating some quite nice renders.
2d black white image generated with processing, the color coded to generate a 3d point cloud with processing, applying 3d delaunay triangulation with tetgen then rendering in meshlab
3D print of a dataform based on 365 days of Canberra weather data (July 08 - June 09). Daily minimum and maximum temperature generate the profile of the outer edge; the holes show rainfall per week. Model generated with Processing, boolean operation in Blender, cleaned in Meshlab, printed by Shapeways. I'll be showing this piece in the Beginning, Middle, End exhibition at ANU School of Art Gallery, 18-24 September - www.bmefestival.com

A group Bronze Age hut circles on Shapley Common, Dartmoor, Devon, UK. These huts were occupied by farmers around 3500 years ago. There are a total of five hut circles at this location with diameters ranging between five and nine metres. The huts have either a single or double layer of upright stones that form the walls. The northernmost hut circle lies within a small enclosure. A later linear bank passes through the site crossing the enclosure and burying the side of one of the hut circles.
Vertical image derived from 3D Model created using Agisoft Photoscan and Kite Aerial Photographs. The top image shows the site coloured and textured with the lighting which was present on the day, the lower image has colour removed and a little artificial lighting direction to help aid interpretation of features.

A small cup-like form derived from 150 years of Sydney temperature data. Treating the form as a stack of rings, each ring represents one year's temperature, with the months arranged radially. The higher the temperature, the further the surface is from the center. Rings are stacked from bottom to top: at the bottom of this form is data from 1859 - at the top, 2009.
Data points are smoothed using a moving average with a five-year span, in order to make the form printable. The data is sourced from the UK Met Office HadCrut3 subset.
The form was generated in Processing, cleaned up in Meshlab and printed by Shapeways in their "Strong White Flexible" material.

Spent some time last night with Pete Prodoehl at the Milwaukee Makerspace playing with taking photos with the Kinect and then printing them out on the Makerbot Cupcake. We also used MeshLab to soften the 3D image before going to print to give the print a smoother finish.

Here's the story on the image itself. Back in 2009 I attended an aviation archaeology field school. (Long, stupid story....) Anyway, I had my pole aerial photography gear with me and a couple of us thought a good way to survey and document the site would be to take overhead shots of everything. We were hoping to stitch them all together to make a photo-realistic map of the site. The images we got were interesting but, unfortunately, we weren't able to combine all the images into the map we wanted. One software package I had heard of was too expensive for us and another that I did get my hands on was too fussy and wouldn't work with our raw images.
A few days ago, though, I learned about a new web site called Hypr3d.com that lets you upload images and it creates 3D models from them. I didn't mess around. I uploaded all 145 clear images we had of this site and let it chew on that overnight. By morning it had produced a rough model I could view in my browser and a higher resolution one that I could download to my PC. I used another application, Meshlab, to rotate it around to the views I wanted and had it render these two images. Both of these views are rendered in "Ortho" mode so there is no perspective. I think that is why it looks less like a photo and more like a painting or model. So, two years after field school ended, I finally have my orthographic projection of the whole site.
In retrospect, I would do this a little differently if I went back. Because all of our images were shot straight down, more or less, there isn't enough information about the vertical faces of the wreck. This shows up as a lot of distorted shapes on the front and sides. We should have taken more oblique shots from the perimeter looking inward. But when you look at the results from an overhead point of view, it looks damn near perfect.

TMR posited it might take half an hour to make a d20 in Sketchup... it took 35-40 minutes, including figuring out a good process.
For the record, I used TopMod to generate the original twenty-face regular solid (it\'s an icosahedron, I believe, but my memory may be faulty), and I also cleaned up in Meshlab (couple clicks just to make sure the mesh was ok).
It Skeined great, at least for the jumbo size dice.
