Reconstruction and manufacturing of existing freeform surfaces are of paramount importance for reverse engineering. These are particularly useful for the situations where the surfaces are partially damaged or the surface models are not available. In order to generate models based on the existing freeform surfaces, the surfaces are first digitized by either a laser scanner or a coordinate measuring...
When a clay model or industrial part is reverse engineered, B-spline surfaces are typically fitted to surface data points collected by a coordinate measuring machine, or, in more recent times, a laser scanner. The surface fitting procedure results in a patchwork of B-spline surfaces. Some of these patches may be required to blend smoothly with their neighbours to a specified degree of continuity....
