On Surface Approximation Using Developable Surfaces

Graphical Models and Image Processing, 1999
Summary: The author introduce a method for approximating a given surface by a developable surface. It will be either a \(G^1\) surface consisting of pieces of cones or cylinders of revolution or a \(G^r\) NURBS developable surface. This algorithm also deals properly with the problems of reverse engineering and produce robust approximation of given ...

Matching of developable surfaces

Proceedings. 1988 IEEE International Conference on Robotics and Automation, 2003
A matching algorithm is presented for the recognition of an important class of surfaces called the developable surface. Such a surface is represented by a line-of-curvature description (LCD). The algorithm matches the LCD of an unknown surface and those of model surfaces on the Gaussian sphere to determine the corresponding model surface of the unknown.

Development of surface display

Proceedings of IEEE Virtual Reality Annual International Symposium, 2002
As a methodology to develop a force feedback system, the concept of "surface displaying" is introduced. A prototype mechanism and its control system is then designed and developed. Methodology for model calculation and simulation is discussed. The idea of texture mapping in a tactile sense is suggested, and is proven to be effective. >

Developable Conditions for Ruled Surfaces and Design of Developable Surfaces

2009 IEEE 10th International Conference on Computer-Aided Industrial Design & Conceptual Design, 2009
With the operator representation of Bezier curves, we first derive the sufficient and necessary conditions of a ruled surface being a developable surface, where the ruled surface is generated from two Bezier curves of degree m and n respectively as its boundary curves.

The Genus of a Developable Surface

Mathematical Proceedings of the Cambridge Philosophical Society, 1935
Cayley's remark that the formula by which the genus of a surface, according to Clebsch's definition, may presumably be computed leads to a negative number in the case of a cone, or a developable surface, or a ruled surface in general, has great importance in the history of the theory.

Tangential developable surfaces as bonnet surfaces

Acta Mathematica Sinica, 1999
Bonnet surfaces are those surfaces in Euclidean 3-space \({\mathbf E}^3\) that admit at least one nontrivial mean curvature preserving isometry \(\Phi\) (here ``nontrivial'' means that \(\Phi\) can not be extended to an isometry of \({\mathbf E}^3\)). A special class \((C3)\) among these surfaces are the ones that admit exactly one such isometry.

The Development of a Surface Arthroplasty for the Elbow

Clinical Orthopaedics and Related Research, 1986
Complex kinematics, anatomical features, and load distribution have contributed to the poor function of constrained and semiconstrained cemented arthroplasties of the elbow. Resurfacing by porous-coated components has the potential, by reproduction of normal joint geometry and restoration of ligament balance, to re-create relatively normal kinematics ...
