recursive field

Nikolaus Gradwohl2016-02-04T09:24:44+00:00

I create a processing sketch that takes an area subdivides it into 9 sub-areas and then randomly fills them or calls it self recursively for the sub-area. This leads to quite interesting forms.

processing blender integration - a first test

Nikolaus Gradwohl2016-01-20T06:19:41+00:00

A view days ago I found the java.blend library by Holger Machens, a java library that allows reading and creating .blend files from java. This opens a whole new range of possibilities for creating blender animations, importing scripted content or using blender to model stuff for interactive applications, and and and. And whats also really cool in my opinion it allows me to combine two of my favorite tools Blender and Processing.

processing blender

I have already ported one of the example programs that comes with java.blend to processing and so far the experiments look very promising.

What this example does is creating a new blend file containing a cube and saving it at "/tmp/copybuffer.blend" This file is used as the clipboard in blender. So when this file exists you can insert its content to the current blender scene simply by pasting it.

to run the code open the sketch in Processing 3, download the jar files from java.blend and drag them onto your script window. This creates a "code" folder for your sketch and adds the needed jars to the import path.

create the copybuffer

when you run the sketch and click on the window you create the copybuffer blend file and can paste it into your blender scene.

paste it in blender

Conclusion: A very interesting new tool - I'm pretty sure I will add more experiments integrating Processing and Blender in the near future - so stay tuned :-)

I created a processing sketch that renders 18 pendulums with slightly different frequencies

Nikolaus Gradwohl2015-06-12T08:19:41+00:00

I created a new sketch in processing that renders some random moving dots and connects them when they are within a certain radius. Click on the image to run the sketch in your browser

I just downloaded the processing pre-release 3.0a8 and tested it with a bunch of parallax flowers - because spring

hexagonal animated texture

Nikolaus Gradwohl2015-05-15T10:47:23+00:00

For this animation I used a similar technique as in my growing-texture animation. I created an image sequence in processing and used it as an animated image texture in blender. I used a transparent material everywhere the texture has a black pixel. The texture is also used as a displacement texture to make the hexagonal tiles better visible

The processing code is based on one of my abstract art generators I have written in processing

growing texture

Nikolaus Gradwohl2015-05-08T06:49:03+00:00

For this animation I used an image sequence to switch between a transparent and an opaque material in cycles.

To generate the image texture I wrote a processing sketch that animates black stripes growing from bottom to top at various speeds. (see below for the sourcecode of the processing sketch)

diffusion reaction in processing

Nikolaus Gradwohl2015-04-29T06:24:04+00:00

A new Pre-Release of Processing has been uploaded to this week, so I wrote a diffusion/reaction-Simulation sketch and played a bit with the various parameters. (Thanks to Karl Sims for this excellent tutorial)

Here is a video and a screenshot of one of the simulation runs
