Playing with POV-Ray
A while ago, I found a great POV-Ray tutorial
on the net. This inspired me to explore this program a bit. The most
fascinating point about POV-Ray is imho that even complex objects can
be designed with only a few lines of code. The following pictures (and
their corresponding scripts) show some examples of my attempts to make
use of POV-Ray.

CeBIT'04 Poster

Lacking any decent DTP software, I decided to create the poster
presentation of the Mikro-SINA project completely via POV-Ray.
I put the core component of our project - the Viaduct - into the
foreground. It is represented by the model of the Blue Wonder Bridge.
I created this model by hand using photographs I found on the internet.
While the bridge is implemented with only 202 lines of code, the
overall scene consists of circa 1600 lines of POV code.

This is the first real scene I made with POV-ray. It illustrates the
microkernel approach we are using for the
Mikrosina project.
The walls stand for address space separation. Communication between
components can only take place by involving the microkernel, which can
enforce a restrictive policy to control information flow between the
components. The scene was taken as basis for the presentation of our
project at the Cebit'03 fair. The scene description file is available
here.
