This research project as described by the list of publications
below has a long history, and the hosting institution
of this web page (TU Graz) has only contributed a small part.
It has been supported by FWF Grant No. P12252 at TU Wien.
Work was performed within the
National research network S92 "Industrial Geometry", funded by
Austrian Science Fund (FWF) in 2005-2010, especially subproject
Computational Differential Geometry.
From 2012, work on developable surfaces is performed within the framework
of the SFB-Transregio programme
Discretization in Geometry
and Dynamics which is supported by Deutsche Forschungsgemeinschaft
in general and by the Austrian Science Fund (FWF, via project I705) in
Developable surfaces are characterized
by being unfoldable into the plane without stretching or tearing.
For all practical purposes this is the same as being composed
of special kinds of ruled surfaces.
We are e.g. concerned with approximation of surfaces by developables,
and in the segmention of freeform surfaces into developable strips.
From the mathematical viewpoint, a series of curves which have
the property that the ruled strips generated by them are developable
(a developable strip model) represents
a semidiscrete conjugate net, so there is an intimate connection
to discrete (actually, semidiscrete) differential geometry.
The property of being developable is highly relevant for
manufacturing, which makes such surfaces useful in various
applied areas, from mechanican engineering to architecture.
