Abstract
We continue to develop the Reverse engineering software MOSAIC. The characteristic functions of MOSAIC generate trimmed NURBS surface quickly without interactive motion, and output suitable CAD like modeling results. At first step, we use the Region Growing with plane proxy for segmentation. At second step, we use the Region Growing with curve surface proxy. We select Non Parameteric Polynomial Surface (NPPS) for curve surface proxy. We think that basic theme generating trimmed NURBS surface quickly was solved.
