Brownian Rain

WOOOOOOOOOOOOHOOOOO!

this is good stuff...
I call it "Brownian Rain," and its going to get better soon. More on this to come as I noodle with it, but so far so good. This is 100 little brownian particles going nuts from random spots around the origin. I want it to spawn around the camera so you are engulfed in them like rain...


Here is a newer variation. The particles spawn all around the camera and have random lifespans. The darker lines are the paths of near-dead particles.

Wow so I just took this idea and ran with it. Here is some more stuff based on the same concept.

These ones are made by introducing a small bias into the randomness so that a particular direction is favored. You can easily see the progression of movement from the particle well (the pointy end) along the bias vector.

I think this is the high point of the website so far. I am quite pleased with these renderings. Keep in mind that all of these renderings were produced with the same algorithm across different instances and with some variable tweaking. This is definitely some of my best work.

Sorry, I am getting a bit excited. There are lots of applications for something like this, though, and it is really fast to compute cause there is basically no computation. The original ball is still the king though.
Ok, then i was thinking, why not add gravitation to the system? I did and this is what it looks like. The particles all start far away from eachother and gradually are sucked together.

So next I had to try something even weirder. I started the particles close together, added in the bias, and adjusted gravitation to the point where the particles gradually start to reach escape velocity. The resulting rendering is a 3D image of what a timeline of the big bang might have looked like. At first its a singularity, but it cannot sustain that level of energy and particles start to seep off its event horizon... ...Then again, it also looks like a piece of celery.
