Three-dimensional animations and visualizations can be of great help to explain flow phenomena, experimental setups and to visualize ideas. Three-dimensional models are also the basis of several of my multirotors. And: They are great fun. I am using several 3D tools, e.g. 3Ds Max and Rhino 3D. Here are some examples of graphics and animations that I created in the past.

An animation of the superhydrophobic surface of a lotus leaf. More images and animations of the effect can be found here. This is my most popular 3D graphic. An incredible amount of books, journals, magazines, websites, commercials, etc. use images and animations from my lotus-effect series.


Yo Fish! The two singing trouts.


An artists impression of a flapping-wing unmanned aerial vehicle.


Leading edge vortices develop during the downstroke on top of insect wings.


Leading edge vortices on the wings of a bird.


This animation shows the setup I developed for my PhD research (time-resolved, three-dimensional flow measurements).


A picture of water droplets on the surface of a lotus leaf.


A not-so-serious animation of a flapping wing micro air vehicle.


The frames of two of my trirotors.


The GEMiNi hexrotor, made for FPV air-races, and tested in a wind tunnel.


The gradient in the effective angle of attack of a non-twisted, flapping wing.


The DLXm mini-trirotor.
