Bit shifting is fun : 1st lesson
Found a nice little trick thanks to this sketch. I was studying the code behind it and this line intrigued me: ellipse(0, 0, halfsize<<1, halfsize<<1); I knew “<<” meant a bitwise operation, but I only saw it in some processing example about faster color manipulation. First time, I see it in a case like this.…

It’s well made and a great way to learn new stuff. The ideal complement to the mother site. All codes are open and freely…

Since there isn’t much documentation for the linux users. I’ll document here my firsts test in getting this library to work under Ubuntu. I…

OpenCV + GStreamer + Camera over IP
It has been quite some time since I was looking for a simple solution for an installation using OpenCV. My main problem comes from the fact that the camera needs to be in perfect alignment with the projector axis (ideally placed right on the projector itself). And until now, I was using a hacked webcam…

Triple Play for “Western” (Saule)
Creation of the scenography and the live video projection tool for the “Western” tour of the band Saule et les Pleureurs. The VJing tool was composed of 3 elements: A video capture system, feeding images and analyzing them, to produce generative art based on the “hot spots” visible on stage. A rostrum-camera used to manipulate…
