On a variational problem due to the B-Darboux frame in Euclidean 3-space

Mathematical Methods in the Applied Sciences, 2021
In this paper, we introduce a new frame which is called the B‐Darboux frame on a surface in Euclidean 3‐space. We know that the parallel transport frame is derived from the Frenet frame along a space curve on a surface. Analogously, we derive the B‐Darboux frame from the Darboux frame along a space curve on a surface in Euclidean 3‐space.

A new version of bienergies and biangles for curves framed by extended darboux frame

Soft Computing, 2021
In this work, we research geometrical interpretation involved with the bienergy by ED-frame fields of the first and second types on an orientable hypersurface in $$\mathbb {E}^{4}$$ . We explore the geometric features of some charts by means of bienergy in

On The Darboux Frame Motion of a Developable Surface

2021
Developable ruled surfaces and the rotation-minimizing frames (RMF) have a crucial importance in computer-aided geometric design (CAGD) because of being unfoldable (developable) into a plane without distortion. Also, the RMF of curves are generally used in computer graphics.

Canonical Decomposition of the Instantaneous Kinematics of Darboux Frame

2020
This paper gives a screw theoretic insight into the instantaneous kinematics of the Darboux frame (D-frame) moving on a smooth surface. It is established that the velocity state of D-frame is described by a three screw system. The principal screws of this system depend only upon the local shape of the surface.

Darboux frames, snakes, and super-quadrics: geometry from the bottom-up

[1989] Proceedings. Workshop on Interpretation of 3D Scenes, 1993
A representational and a computational model for deriving 3-D articulated volumetric descriptions of objects from laser rangefinder data is described. This method is purely bottom up: it relies on general assumptions cast in terms of differential geometry.

Estimating the principal curvatures and the Darboux frame from real 3D range data

Proceedings. First International Symposium on 3D Data Processing Visualization and Transmission, 2002
Principal curvatures and the local Darboux frame are natural tools to be used during processes which involve extraction of geometric properties from three-dimensional (3-D) range data. As second-order features their estimations are highly sensitive to noise and therefore, until recent years, it was almost impractical to extract reliable results from ...

On the Parallel Ruled Surfaces with B-Darboux Frame

2017
In this work, the geometric properties of parallel ruled surfaces associated with the B-Darboux frame (BDF) in $E%%TCIMACRO{\U{b3}}%%BeginExpansion{{}^3}%%EndExpansion$ are introduced. Firstly, these surfaces are presented, and their main characteristic properties, such as developability, stress points and dispersion parameter, are analyzed.
