A Perlin-Noise Force-Field

Nikolaus Gradwohl2011-11-08T06:06:45+01:00

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

bubble emitter

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

Project-Page for Animator-library

Nikolaus Gradwohl2011-11-05T11:35:31+01:00

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

first Alpha-Version of a Animator-library for Processing

Nikolaus Gradwohl2011-11-04T04:29:55+01:00

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


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.

first impression of processing2.0a2

Nikolaus Gradwohl2011-11-03T06:20:31+01:00

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 :-)

fading dots

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? :-)

foggy wood with recursive trees

Nikolaus Gradwohl2011-10-30T08:27:59+01:00

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.

isometric labyrinth

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

I made a simple gauge simulator in processing

more processing lineart

Nikolaus Gradwohl2011-10-25T07:36:33+02:00

And here comes another example of interactive lineart in processing. I'm quite sure its not the greatest example if interactive art, but I still like it.
