Multi-dimensional dynamic programming in ruled surface fitting

CAD Computer Aided Design, 2014
Ruled surfaces play an important role in many manufacturing and construction applications. In this work, we explore a multi-dimensional dynamic programming based ruled surface fitting scheme to a given freeform rational surface, S.

Quaternionic Shape Operator and Rotation Matrix on Ruled Surfaces

Axioms, 2023
In this article, we examine the relationship between Darboux frames along parameter curves and the Darboux frame of the base curve of the ruled surface. We derive the equations of the quaternionic shape operators, which can rotate tangent vectors around ...

Principle and Method for Machining Face Gear with Developable Ruled Surface

Xibei Gongye Daxue Xuebao, 2020
The tooth surface of a face gear is recognized as un-developable ruled surface in tradition, which result in the problem that face gear generation using simple cutter with high efficiency and accuracy puzzled people for a long time.

Characterization of rational ruled surfaces [PDF]

Journal of Symbolic Computation, 2014
The ruled surface is a typical modeling surface in computer aided geometric design. It is usually given in the standard parametric form. However, it can also be in the forms than the standard one. For these forms, it is necessary to determine and find the standard form.
