sketch2sketch is a short Ruby script that I developed. It enables you to export Google SketchUp models to the 3D scene description language Sketch from Eugene Ressler. Sketch is a system for producing sketches of 2D or 3D objects and scenes. It produces TikZ code that can be directly used in TeX/LaTeX documents.
Previously I wrote about Structure from Motion using Bundler. If you have troubles with these Linux command line tools, you might want to try Microsoft Photosynth. You simply select the images on your hard drive and wait the software to align all cameras, basically the same way Bundler would.
(Ok, first you need to download a piece of software and create a Windows Live ID… But as a brave Linux user you are running such Microsoft programs in a Virtual Box. So it doesn’t do too much harm.)
Ribana and I developed a combination of subspace methods and a low-dimensional linear transformation to find relations between similar manifolds from different datasets. One application was to relate real world faces with cartoon images from The Simpsons Movie Website.
