Towards an automatic geometry conversion: TGeoArbN — a ROOT-compatible triangle mesh geometry implementation [PDF]
EPJ Web of ConferencesTGeoArbN is developed as a tool to automate the process of converting Computer Aided Design (CAD) models into ROOT geometries for physics simulations using the Virtual Monte Carlo (VMC) package. ROOT’s geometry package currently has a capability gap when

Segmenting Periodic Reliefs on Triangle Meshes [PDF]
, 2007 Decorative reliefs are widely used for e.g. packaging and porcelain design. In periodic reliefs, the relief repeats a pattern, for example all the way around an underlying surface of revolution. Reverse-engineering of existing reliefs allows them to be re-applied to different base surfaces; we show here how to segment a single repeat unit of a periodic
