✦ Synopsis
others, which are transverse generatrices. Jones ('Shape control of curves and surfaces through constrained optimization') studies the possibility of local alteration to avoid irregularities and obtain, in the meantime, inflection regions.
By relating discrete values of a variable to some points scattered on a previously defined surface, Barnhill, Piper and Rescorla ('Interpolation to arbitrary data on a surface')interpolate these values for any point on the surface. For instance, if pressure is measured on some points of an aircraft wing, the resulting lift can be computed.
Munchmeyer ('Shape interrogation: a case study) investigates the properties of given shapes: Gaussian curvature, mean curvature, principal curvatures, asymptotic directions, etc. Each is expressed using a graph, through which many other properties become obvious.
