The geometrical modelling part of simulations is of central importance in nearly all applications. Apart from the pure construction of curves and surfaces, the analysis of their quality is equally important in the design and manufacturing process. It is, for example, very important to test the convexity of a surface, to pinpoint inflection - points, to visualize flat points and the technical smoothness of surfaces. We have developed special algorithms to deal with these kind of problems. At the present time our solutions are state of the art in industry , but at least one interesting problem is not solved yet :
Aesthetic Feature Modelling
Aesthetic aspects of surface modelling are currently "tested" by simulations of reflection line patterns.
