Polar forms for geometrically continuous spline curves of arbitrary degree
HP Seidel - ACM Transactions on Graphics (TOG), 1993 - dl.acm.org
This paper studies geometrically continuous spline curves of arbitrary degree. Based on the
concept of universal splines, we obtain geometric constructions for both the spline control …

Deriving the beta-constraints for geometric continuity of parametric curves
Parametric splines curves are typically constructed so that the first n parametric derivatives
agree where the curve segments abut. This type of continuity condition has become known …

Computer aided design of developable surfaces
BE Konesky - 1993 - open.library.ubc.ca
The design of objects employing developable surfaces is of engineering importance
because of the relative ease with which developable surfaces can be manufactured. The …
