文档介绍：Geomagic Studio Demo
Point Cloud to NURBS Surface
Objective: Starting with a point cloud, demonstrate the workflow of Geomagic Studio to the
customer, emphasizing the speed and timesavings of the automatic patch
construction technique with minimal editing.

cloud into a CAD-ready surface model in about
15 minutes. The process involves three basic
types of entities: points, polygons (or triangles),
and surfaces. We will begin with points.

minimize the problem by identifying noisy points
and moving them to the local average surface to
improve the data quality.
