Bonnet Ruled Surfaces

Acta Mathematica Sinica, English Series, 2005
Bonnet surfaces are those immersions into Euclidean 3-space whose congruence class is not uniquely determined by their metric and mean curvature. As already proven by Bonnet, all Bonnet surfaces belong to one of the following classes: constant mean curvature surfaces, Bonnet families and Bonnet pairs.

On the Curvature Functions of Ruled Surface

International Journal of Computational Geometry & Applications
We considered differential geometries of helical curves for ruled and developable surfaces in Euclidean 3-space E 3. We clarify the conditions for ruled surface to become stationary-axis ruled surface. Then, we concentrate on ruled surface generated by a line undergoing a one-parameter screw movement. Finally, we provide some modules to illustrate the

Rational Ruled Surfaces and Their Offsets

Graphical Models and Image Processing, 1996
Abstract In this paper, geometric design problems for rational ruled surfaces are studied. We investigate a line geometric control structure and its connection to the standard tensor product B-spline representation, the use of the Klein model of line space, and algorithms for geometry processing.
