physical landscape models are usually based on
real elevation data collected by satellite measurements. They reflect
the morphological features of the earth's surface very precisely. However, in
certain contexts one would like have more freedom in design and
would instead create fictional landscapes that are better suitable
for example for the simulation and animation of geological
processes. The current project "Tropical Paradise Lausitz? - Climate
Change in Tertiary" in a special exhibition at the Museum of
Western Lausitz in Kamenz offered this opportunity.
The familiar landscapes of coastal regimes
change barely in human time scales. Discussions in the context of
climate change indicate future developments that,
however, correct this static picture markedly. Even more
geological observations reveal dramatic sequences of rising and
falling relative sea-level, circumstances in which even entire
continents were flooded or fell dry again. These complex issues
should be made imaginable to layman in an animated form by an
interactive landscape model .
The 3D-modeling of digital terrains is a
powerful tool to manipulate existing landscape data or to create
entirely new landscapes. Initially, for example, the CNC
manufactured relief model based on real elevation
data of the Elbe estuary region, which were later changed to such an
extent that a classical delta complex is formed.
For further smooth animation of geological
processes many more sets of different landscapes had to be
developed. All of which are used for vertical projection onto the
physical terrain model. However, note that all
fictional digital data sets would principally also fulfill all
requirements to be machine milled (CNC) into solid terrain models.
This offers a wide scope of totally new applications.

The main aspect of the current project was to
provide some insight into the interaction between land and sea
and its responsible causes in a playful way. For this purpose the
users are successively introduced to the complex matter and can
by trial and error or by forward-backward developments get a feel
for the factual context.
A relatively simple experiment
allows making the sea level rise and fall - a short video you
may find here.
How complicated interactions of land and sea can
be, is shown with an "experimental station", where different
parameters can be set. The resulting changes to the landscape are
projected on the relief model as a flowing development - a short
video can be found here.
The ultimate discipline is finally a complete
geological history that takes place synchronously in the geological
cross section and as a fully animated projection on the
physical relief model.

Particularly geologic and
geographic aspects can be animated in a very impressive
manner using digitally 3D-modeled terrains.
Furthermore the resulting database developed
from 3D data can also be used directly at the CNC fabrication of
physical relief models.
