de jong attractor

I've been experimenting with strange attractors lately and this is one of the processing sketches I created - showing a animated version of the de jong attractor

floating rectangles in processing

Nikolaus Gradwohl2019-07-14T11:13:43+00:00

I created some floating rectangles in processing, that change their position and size and morph between the current and the new state

corral structures from particle collisions

Nikolaus Gradwohl2019-07-09T06:53:47+00:00

I wrote a processing sketch that creates 2D corral like structures, by throwing a group of particles at a center location and making them stick whenever they hit another already sticked particle

corral

the sketch starts by initializing a sticky particle at the seed location and then placing all other particles at random locations with their direction vector pointing to the seed particle

then each particle moves in the direction of the center and if it hits an already sticky particle it gets sticky as well. When two nonsticky particles collide, they get shifted around a to a random position to prevent them creating endless loops.

raindrops processing sketch

a short processing sketch drawing raindrops on a surface maybe I turn this into an animated texture for a blender render

Phase Shift

Nikolaus Gradwohl2019-06-13T03:31:14+00:00

I made a video for my track "Phase Shift" in processing.

The song is two lines playing the same melody, but with different loop lengths - shifting in and out of phase

The animation was generated from a wild combination of trigonometric and noise functions generating 7200 curve vertices that are slowly changing over time

processing symetrie explorer

Nikolaus Gradwohl2019-03-06T03:13:22+00:00

I created a little processing sketch that draws a filled curve at some random vertices, and then mirrors it and draws it a second time. I like how simple evolving shapes that are drawn twice mirrored along an vertical axis immediately look very organic. So watch the shapes evolve slowly and have fun finding flowers, faces, insects, ...

processing sound visualizer explained

Nikolaus Gradwohl2019-01-22T05:07:16+00:00

I have been asked to share the code of the sound visualizer I wrote in processing about a year ago, so I decided to write a blogpost explaining what I did

The program has two main parts - the autocorrelation function that creates the wiggly line and a glsl filter for the lens-distortion effect.

polar coordinate pendulum on a sphere

Nikolaus Gradwohl2018-11-26T04:23:44+00:00

I took my last processing sketch to the next level and instead of making the pendulum swing on a plane using polar coordinates i made it swing on the surface of a sphere by keeping the radius fixed and changing the two angles of a spherical coordinate set. Then I created a curve out of the last view points and rotated the whole construct a little bit to make the 3D effect more obvious.

polar coordinate pendulum in processing

Nikolaus Gradwohl2018-11-24T04:54:52+00:00

I wanted to explore motion using polar coordinates that's restricted to the inside of a unit cycle - so I created a processing sketch where the radius and the angle of a poolar coordinate vector oscillate using some trigonometric functions with different phasing and periodicity, converted them to Cartesian coordinates and made a small blue dot following the line.

If you read the above paragraph without leaving - contratulations! - here is a small blue dot creating a wiggly line inside a circle - as a reward :-)

customized coffe mug with processing

Nikolaus Gradwohl2018-11-07T04:18:42+00:00

I got a coffee mug as an advertising present recently but it hat a huge company logo on it and since I don't like to run around as an walking advertising board I didn't really use it. Fortunately I saw this weekend, that the inner part of the mug can be removed and the company logo is only on a sheet of paper between the outer and the inner shell of the mug - Sooooooo - I fired up processing created a cool pattern using lots and lots of sine wave plots and printed it on a sheet of paper - then I cut it to size using the original inlay as a template and voila! a new customized and exchangeable inlay for my coffee mug - now I can use it to bridge the coffee availability gap between the coffee machine at home and the coffee machine in the office.

if you want to recreate the pattern or use it as a basis for your own pattern generation sketches, you can see the code here.
