The problem of computing a geodesic on a discrete surface is an example
of discrete differential geometry. In this field a more than active
research is going on. For people interested in results and algorithms
rather than implementations in vtk I can recommend
http://www.zib.de/geom/ , a group of mathematicians at
Konrad-Zuse-Zentrum in Berlin / Technical University Berlin, Germany,
who work at the cutting edge of this field. They have their own
visualization for those problems called JavaView (www.javaview.de) which
is absolutely worth looking at.
