This paper studies how to generate the slice data from point clouds, which is the critical problem in the integration of Reverse Engineering and Rapid Prototyping Manufacturing. At present, there are two ways available. In the first
path, a CAD model is created first from point clouds then converted to a STL file. The STL file is then sliced to generate a series of layers for RP fabrication. The second path is to create the STL file directly from point clouds. However, there are drawb...
