Web2 Radius of Curvature and Total Curvature circle center of curvature osculating curvature radius of 1/κ α(s) When the curvature κ(s) > 0, the center of curvature lies along the direction of N(s) at distance 1/κ from the point α(s). When κ(s) < 0, the center of curvature lies along the direction of −N(s) at distance −1/κ from α(s). In WebMar 24, 2024 · The curvature at a point on a surface takes on a variety of values as the plane through the normal varies. As varies, it achieves a minimum and a maximum (which are in perpendicular directions) known as the principal curvatures. As shown in Coxeter (1969, pp. 352-353), (47) (48) star of babalon
