: Current feature modelling systems suffer from a number of shortcomings. One is that the meaning of features is often not adequately maintained during modelling, which implies tha...
The protocols selected and developed by the NIIIP Consortium have been validated in three end-of-cycle demonstrations. In each cycle, a team with expertise in technical product da...

This paper presents an algorithm for extending B-spline curves and surfaces. Based on the unclamping algorithm for B-spline curves, we propose a new algorithm for extending B-spli...
Abstract. This paper presents two automatic fairing algorithms for parametric C2 -continuous bi-cubic B-spline surfaces. The fairing method consists of a knot removal and knot rein...
This article presents an efficient and robust algorithm that computes the intersection curve of two ruled surfaces. The surface intersection problem is reformulated as a zero-set ...
