e/Surface-to-surface intersection problem

Information
has gloss	eng: The surface-to-surface intersection (SSI) problem. is a basic problem in computer-aided geometric design: Given two intersecting surfaces in R3, compute all parts of the intersection curve. If two surfaces intersect, the result will be a set of isolated points, a set of curves, a set of overlapping surfaces, or any combination of these cases . Because exact solutions can be found only for some special surface classes, approximation methods must be used for the general case.
