Geometry data is delivered as points in a cartesian coordinate system after a 2D-/3D-surface scan or a CT analysis of a part.
The sum of all points is called point cloud.
On the base of the point cloud triangle elements will be created in order to visualize the skin of the scanned object.
A return of the data into a CAD model is possible based on a point cloud as well as on the base of the generated triangle element-mesh.
It has to be noted, that the quality of the CAD surfaces show imurities.
