Signed curvature function

WebMay 1, 2024 · For planar curves, most efficient methods for blending between two closed curves are based on the construction of the morph curve involving its signed curvature function. The latter is obtained by linear interpolation of the signed curvature functions of the source and target curves ( Sederberg et al. (1993) , Saba et al. (2014) and Surazhsky … Websign is only a convention and simpli es some notation later). ˝(t) is a new term that cannot be written in terms of known terms like the curvature etc and is called the \torsion" at t. We have shown that the derivatives of T(t), N(t), and B(t) can be written in terms of the basis fT(t);N(t);B(t)gand the coe cients depend only on the

The second derivative is something like curvature, and the second derivative of sin(x) is -sin(x). The negative sign suggests that if we look at signed curvature rather than absolute curvature, then the values of a sine curve are roughly proportional to the negative of the curvature at each point. ion h0-
