Intersurface continuity of B-spline based solid models | One of the issues of concern in any boundary representation model is the smoothness at the abutment edges of the model surface patches. This thesis looks at the maintenance of this smoothness (continuity) between connected B-spline surfaces in a multi-surface model. This process also necessitates ad... | computer graphics; computer aided design | 1988-08 |
