| Abstract: | Discusses some algorithms and their applications on NURBS. the NURBS interpolation algorithms don' t only interpolate data points, but also interpolate the weights on the data points. NURBS holds degeneration cases. By dealing with them, varies of sculptured curves and surfaces are obtained easily. Last, some special modeling methods on NURBS are provided, such as drive surfaces and skin surfaces. etc. All express the domain of NURBS is very wide and the use of NURBS is flexible. Above algorithms are realized in the CAD/CAM system-SUMS, developed by Beijing Univesity of Aero. and Astro. |
