Reverse engineering closes the loop with Computer-Aided Design (CAD). While CAD starts from a design of a shape model toward a computerized model to be fed to a Computer-Aided Manufacture (CAM) system, reverse engineering starts from measures (like photometric data) of existing components, to obtain a digitized model which needs then to be transformed into shape models, a process we call ``Geometric Modeling''. Typically, the input data will consist of a set of unorganized data points in 3D space.
Noticeably, we will address the need to model and manipulate both regular and free-form shapes, preferably through non-invasive measurements (e.g. photos, videos, etc., but certain other sources of input data, like from laser range should be used as well).
