Geometry

Part of my research evolves around geometric modelling with some topics related to computer graphics and vision. A particular direction is reverse engineering in the sense of generating computational descriptions of artefacts and natural objects and detecting patterns in the measured data suitable for analysis, modification and simulation applications. I am also working on point-based modelling, curves and surfaces, mesh processing, and related issues in differential and computational geometry.

Monster Overview
Our approach is based on two ideas: (1) decomposing a model into suitable sub-parts simplifies finding regularities, which are less ambiguous compared to analysing the model as one part; and (2) detecting approximate symmetries and related regularities reveals a likely design intent description, but requires careful handling of tolerances to […]

FReg is the implementation of an algorithm to detect approximate symmetries of point sets and B-rep models. It has been developed as part of the Beautification of reverse engineered geometric models project. The algorithm has been implemented originally by B. I. Mills. I am currently maintaining the sources. The main […]

SiL is an environment for geometric modelling applications. It’s core is an object manager especially tailored for geometric objects. It can load modules dynamically to provide the object types and the basic functionality for these objects. In addition tools can be added as plugins to provide a user front-end to […]
