To obtain the initial data for a part we use a commercial 3D laser scanner. From the generated point clouds a valid CAD model can be created by using existing technologies. This can be done by segmentation of the point sets into subsets and by finding surfaces that best approximate […]

LiLit is a program to visualize functionals on freeform surfaces. It uses biquadratic g-splines to display surfaces and functions, which are defined by a control mesh for the surface and the function from some file in a special input format. It can run the Doo-Sabin subdivision algorithm on the control […]

DeLia intends to address those problems as a universal packaging, configuration and administration system. Instead of setting exact requirements for the configuration of a system the intention is to provide a flexible approach to the configuration within a fixed, but general framework of options. However, at this stage it does […]
