  • 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.…

  • 200 Characters Processing Competition

    200 Characters Processing Competition

    OpenProcessing and Rhizome joined forces and setted up a contest inviting artists and programmers to propose their best Processing sketch with this 2 creative constraints: in 200 characters maximum, with no external files. And it’s exactly those 2 constraints that kept me busy. I already had worked on a project where a program displays its…

  • 1st sketch @OpenProcessing

    It’s been quite some time since I’ve been following OpenProcessing. The idea behind the website is simple: allow anyone to post some Processing bits of code and share it with others. 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…

  • Carnivore library under Ubuntu

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…

  • Journées du libre 2009 : Poster

    Like last year, I was contacted to design the poster for the Journées du libre. And like last year, I wanted to do it again using Processing. But this time, I let down the concept of a purely GPL poster to concentrate on the informations displayed on it, as suggested by the organizers. Anyway, I…

  • OpenCV + GStreamer + Camera over IP

    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)

    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…
