# Beautification

- Reverse Engineering and Beautification of Geometric Models[More]
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 those subsets. From these surfaces ...
