In this paper we study the pairs of orthogonal foliations on oriented surfaces immersed in $\mathbb{R}^3$ whose singularities and leaves are, respectively, the umbilic points and the lines of normal mean curvature of the immersion. Along these lines

This study presents a new method for reconstructing an underlying surface from scanned data of styling design objects. Our approach is based on sweep-based modeling, in which a surface is generated by sweeping a specified section curve along a 3D spi

In biangular coordinates, a G 1 Hermite interpolation reduces to the problem of choosing appropriate functions interpolating the coordinates of the curve at its endpoints. The simplest linear equations in biangular coordinates correspond to a sectrix

We present a method for constructing almost-everywhere curvature-continuous, piecewise-quadratic curves that interpolate a list of control points and have local maxima of curvature only at the control points. Our premise is that salient features of t

The total mixed curvature of a curve in $$E^3$$ is defined as the integral of $$\sqrt{\kappa ^2+\tau ^2}$$ , where $$\kappa $$ is the curvature and $$\tau $$ is the torsion. The total mixed curvature is the length of the spherical curve defined by th

Let f be a function with certain properties and $$\gamma $$ be a closed curve with the torsion $$\tau $$ . We prove that $$\oint _{\gamma }f\tau ds=0$$ if $$\gamma $$ is a spherical curve, and conversely, if a surface makes the integral equal to zero

In this paper, when the Frenet vectors of the partner curve of Mannheim curve are taken as the positionvectors, the curvature and the torsion of Smarandache curves are calculated. These values are expresseddepending upon the Mannheim curve. Besides,

We continue our analysis on functionals depending on the curvature of graphs of curves in high codimension Euclidean space. We deal with the “elastic” case, corresponding to a superlinear dependence on the pointwise curvature. We introduce the co
