On Relatively Normal-Slant Helices and Isophotic Curves
arXiv:2104.13220
Abstract
In this paper, we give smoe characterizations of relatively normal-slant helices and isophotic curves on a smooth surface immersed in Euclidean 3-space with respect to their position vevtor. We also introduce the methods for generating an isophotic curve on a given surface by its parametric or implicit equation.
