Lab : Light Particles Interacting with Obstacles.

August 10th, 2010

Time ago, I found a experiment with particles on the site "asluv.com".

I like it, but it was a little slow, so I decide to change the code a little, and just avoiding the use of sprites, I got a great improvement on the speed.

This AS3 experiment uses a BitmapData to determine whether the particles should change their speed in function of the background color of the bitmap.

There is a GlowFilter and BlurFilter applied to the particles, to create a nicer visual result.
Playing just with the filter, we can get very diferent and nice result.

Lab : How to use Perlin Noise to generate Fire.

July 14th, 2009

The Tron (1982) movie, in addition to inspiring me and a lot of people of my generation when we were younger, was also a pioneering effort for computer-generated graphics in film.

Ken Perlin, who worked on Tron was frustrated by the "machine-like" appearance of the models in the movie, and then he developed a method of creating textures with a mathematical algorithm that could be applied to images to introduce that random quality that real world has, less perfect computer-generated imagery.

These procedural textures can be used to lots of things, but I focused on a way generate smoke,fire and water surfaces.

Lab : Drawing with the flash API.

November 29th, 2008

When I had to replicate the 80's lava lamp object, my first thought, was to create a complex particle system, and use the drawing api to draw a gradient simulate the plasma effect, but after a while, I found that using blendModes,combined with gradient colored circles, simplify the problem to the limit.

Blend modes are conceptually very simple, but their practical application is sometimes difficult to see, and really often does result only from a bit of luck and guesswork.
