Two new papers were added to the publications page. These papers reference  my work on the real-time simulation of muscle action lines to measure muscle elongation during complex motion. Based on a position-based-dynamics technique, I implemented a real-time multi-threaded simulation of muscle action lines in combination with continuous collision detection. The results of the work of my co-authors is illustrated in the video below, with my contribution visible from the 1m18 mark.


“So you work at Artanim, right?” “Yes indeed, since last December.” “Great, and what is it you do there as a senior researcher in computer science?” “I do voice-overs.” “Of cour…what?”

Of course that is not my primary task description, but it is the first minor contribution I can publicly show. Artanim, together with several partners, performed an interesting study into the risks related to sexual activity after total hip arthroplasty (THA), and accompanied it with a video. And after my previous voice-over for the award winning “Illusion of Intelligence”, how could they not ask me? So here it is, for your enjoyment.

I soon hope to update you on some of my actual day-to-day work, but until then you can dream away at the soothing tone of my voice.

If you’d like to know more about the research itself, or the work we do, then visit the project’s page or the general website.

Our video “The Illusion of Intelligence” has won the award for “Best Student Video” at the AAAI 2012 Video Competition.


The illusion of intelligence is a video from Karolina Zawieska, Bart Kevelham, Maher Ben Moussa and Nadia Magnenat-Thalmann.
Created at MIRALab – University of Geneva, the video discusses the human tendency to anthropomorphise machines, in particular to project intelligence onto robots.


Our paper Virtual try on : an application that needs GPU acceleration has been published as part of the ATIP – A*CRC Workshop on Accelerator Technologies in High Performance Computing.


In this paper we discuss our Virtual Try On (VTO) from the perspective of performance. The VTO is an application which assists users in the evaluation of physically simulated garments on a size-correct virtual representation of their own body. Where in previous work we discussed its features and implementation, here we analyze its performance and identify those components which would benefit most from additional optimization efforts. We then detail our ongoing efforts and achieved results with regards to the optimization of the application, by making use of GPU computation, focused on the accurate physical simulation of garments.
