All computer graphics images are designed using Blender, a free and open source 3D creation suite (see Some images were partly generated using Matlab and were only embeded. Here are only a few of my hobby projects shown.

This image is based on an introductory tutorial (CG Boost). I have added a red wine glass. Here, I wanted to see how I can use gravity to let rigid bodies adjust to their environment in blender.
My first project following the tutorial of Blender Guru showing my personal interpretation of a donut and a well shaped coffee mug. The latter is an important tool to work efficiently in science. ;-)
This illustration highlights my Diploma thesis. I used the materials for Enceladus and the Cassini spacecraft that are available at the NASA homepage. It's simple, but nice.
This image is supposed to highlight the mechano-sensing of motile cells on rigid substrates. My kids called it the monster cell. I build it up from skratch and used a wave-let generator in blender.
Here I tried some new features in Blender 2.80 using Fresnel effects, emission shading, and noise texture mapping.
This graphic started as a project for a potential journal cover of a paper. A similar version of that graphic got published as a homepage banner for the Biophysical Journal in 2019.
Followed a tutorial to create 3D fractals by Bad Normals for the new Geometry Nodes in Blender (Ver. 2.83). An easy way to conect the math with the objects. Impressingly easy.
The result of a short introduction of Blender to a student, who wants to create some impressive schemes for a paper.
First trial to make a hologram effect using Geometry Nodes. Added a moon-like surface and some random stars.
Hologram of a realistic heart with a single light source.
