On The Darboux Frame Motion of a Developable Surface
Abstract
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. In this paper, we discuss the relationship between spherical motion and a developable ruled surface that has a line of curvature as a base curve. On the other hand, we use spherical linear interpolation (SLERP) to analyze the relationship between the trajectory generated on the unit sphere due to this spherical motion and the inflection curve.
Moreover, we examine some invariant values of this developable ruled surface. We also present the S.Frenet frame of this trajectory based on general quaternion frame equations.

We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
