this little sketch was developed more on chance than on purpose, I was playing around with sin waves and visualizations of fft-spectra when I came up with this - It reminds me a bit on my first experiments with sine and cosine on my old Atari ST.

I made a processing sketch featuring a chaotic cpendulum - well not quite chaotic but it has a veeeery long periode before the pattern is repeated exactly

I made a processing sketch today that shows some particles move in a perlin-noise based force field. The field changes at random times

I made another processing sketch featuring bubbles - this time the bubbles are emitted from a central particle emitter and fade to black as they grow

I just made a Project-page for my animator-library

I also started adding some basic Documentation and added a download link to the source-code which I totally forgott in the anouncment blog post

I'm currently working on an animation framework for processing. It's currently very unpolished but following the open-source mantra "publish early - publish often"

tadaaaa! - here is the first alpha-version

to install it unzip the package in the library folder of your sketchbook

There isn't much documentation yet (*looking ashamed*) buuut I made a short example sketch to show how it's used.

an Animator object can be defined using

Animator a = new LinearAnimator( time, startvalue, stopvalue );

it's started using

a.start();

and the current value can be fetched using

float v = a.get();

I currently implemented a LinearAnimator-, a SquareAnimator- and a RootAnimator-class.

I plan implement chaining of animators, callback-handlers, repeat suppor, many more animation types and - ahem - more detailed documentation

Feedback is very welcome.

A click with the left mouseButton starts the animation of the circle.

A click with the right mouseButton start the animation of the square.

I downloaded the 2nd alpha version of processing 2.0 yesterday and played a bit with it. The first two things I noticed are that processing switched to gstreamer for playing videos! finally! I really love this, because I mainly use processing on my linux box and had to install it my hand.

The second thing that cougt my eye is that the modes list has been extendet by a javascript mode. So you can write a processing.js, a classic processing and an android version of a sketch using the same ide just by switching modes - very nice!

There are tons of other improvements and little changes I haven't tried yet, but the switching of the video framework alone makes it worth upgrading :-)

I'm playing with animations currently and this is a simple test of animating the fadeout of objects. In this case I animate small circles that appear in the screen and then fade into nonexistence - just to reapear anywhere else on the screen. Sounds very philosophical for some simple fading dots - doesn't it? :-)

My latest processing sketch draws a wood of recursive generated trees. To add some pseudo 3D effect, the trees are drawn smaller and lighter the further they are away from the viewer.

I also added a little noise to the angle of the branches to simulate a little bit of wind.

I combined two of my older processing sketches - the labyrinth generator and the isometric drawing example
