In the past few days i was playing with voronoi cells. in the meantime i had another idea i wanted to try: random recursive cell growth. So i started working on both pieces together and came up with what you’re about to see in the videos below.
The scene is rendered using a per-pixel phong lighting model + wrap lighting, a fast trick to approximate subsurface scattering. More information available in the GPU Gems book.
I have used lee byron‘s mesh library for the 2D voronoi mesh generation and loaded it up my framework to generate a 3D heightmap mesh. I’ve reduced the effect to almost zero here, just because i think it looks much better flat in this particular scene.
A few days ago i visited Mathieu Badimon’s website and i found myself playing with one effect he made for Five3D website. The trail effect.
It’s a pretty simple effect but he made it go further, he created it using his own 3d framework for Adobe Flash and has a particular thing that I like a lot. The drawing in perspective and that simple but incredible sweet pass over the top plane.
Well I had to give it a try and after fiddling around the web and talking to some people I’ve created a version of his effect. By all means, i release this code to the public with Mathieu’s authorization, even if its my code, it was his idea in the first place.
Note: There are two versions of this effect available. 1st uses Five3D, 2nd using only flash.
I’m working on a version that uses Sandy3D for rendering. It will soon be available, meanwhile you can download other versions and play around.
You can find a Sandy3D example of this effect here. What i do is just the same as the simple version. Draw into a sprite object and attach this to the material used in a plane polygon. Sandy converts vectordata into a bitmap, so things didnt came up as i expected.
I was browsing around, and i have noticed an effect implementing repulsive forces. i wanted to give it a try and i came up with this piece. made with a few hundreds of particles and two repulsive point forces. reacts to audio input. built with processing. you can watch or download it.
