These last two weeks I've been pretty distracted with personal issues, and to get back on track it always helps me to start a small personal project in which I experiment something I've never done before. So here we go: GPU Raymarching using Distance Fields.
This project is completely based on the work of Iñigo Quilez, the great IQ from rgba. He put some slides in his website explaining how to do this kind of rendering, and after reading them I just had to try it for myself.

Little test to see what can you do to approximate a big image using only a few samples, and using Voronoi diagrams for that. It's not amazingly cool or anything, but it runs in real-time :)

Hi there! New blog (again), I hope this one lives for more than 2 years...
This last year I got really tired of Drupal, and decided to use something else and create another blog. In the end (after some googling), I decided to go with Movable Type. It's much more organized and stable than Drupal, and has almost no cpu cost for each page view (pages are generated just once as an html, instead of each time a user views the page, like Drupal does). I hope it doesn't give me as many headaches as the old web did...
Also, I've decided to write in english from now on. Almost everyone that read the previous blog knows english, so I won't be losing lots of readers (except my mother. Sorry, mom). And more importantly, this way I get to practice my written english, which has always been my weakest and was weakening by the moment.
And about the page itself, I'm not entirely convinced of the page design (it's just a default theme with a changed header), but it'll have to do for the moment. My design skills aren't really the best, and my designer friends are all too busy to work for free (or in exchange of a couple of beers).
Anyway, to start filling this new web with something useful, I've uploaded a new video showing the output of my software raytracer (anyone remembers?). It's just that I recently upgraded to a quad core machine, and had to test the machine with a heavily multithreaded program :)
So, here's the video (it's in full HD, so hit the fullscreen button!):
The video is also linked in the Software Raytracer page in the Projects section, by the way ;-)
