These patches are constructed separately from the data local to the patches, and sewed together. This construction makes it possible to approach really huge data sets, as well as controlling the approximations locally. Geological modelling Modelling geological subsurfaces involves gridding of large data sets subject to various types of constraints such as geological faults and range restrictions.
Data stemming from seismic surveys are also subject to noise.
Medical modelling Medical geometry is often represented with 3D contour slices. CAD and reverse engineering Reverse engineering in CAD is about the construction of smooth CAD models from measurement data, e.g. from a clay model. The contract work is based on the Siscat and SISL libraries. Terrain modelling Siscat contains a lot of functionality for constructing terrain models. Here we focus on terrain modelling with the Siscat triangulation module.
