Analysing the variations of shapes based on surface-models

In this paper we present a freely available application with which surface models, e.g. triangle meshes can be registered rigidly as well as by using similarity or affine transformations. Registered surfaces can be analysed, i.e. their difference can be calculated and visualised in various ways. The software is addressing the problem of evaluating shape differences of generated surface models due to mesh relaxation, decimation, object (in our case: patient) variation, different co-ordinate systems, etc. We invite all interested research personnel to download and use the software.
