//! Describes functions for computing all the extrema
|

//! between two surfaces.
|
|
//! An ExtremaSurfaceSurface algorithm minimizes or
|
|
//! maximizes the distance between a point on the first
|
|
//! surface and a point on the second surface. Results
|
|
//! are start and end points of perpendiculars common to the two surfaces.
|
|
//! Solutions consist of pairs of points, and an extremum
|
|
//! is considered to be a segment joining the two points of a solution.
|
|
//! An ExtremaSurfaceSurface object provides a framework for:
|
|
//! - defining the construction of the extrema,
|
|
//! - implementing the construction algorithm, and
|
|
//! - consulting the results.
|
|
//! Warning
|
|
//! In some cases, the nearest points between the two
|
|
//! surfaces do not correspond to one of the computed
|
|
//! extrema. Instead, they may be given by:
|
|
//! - a point of a bounding curve of one surface and one of the following:
|
|
//! - its orthogonal projection on the other surface,
|
|
//! - a point of a bounding curve of the other surface; or
|
|
//! - any point on intersection curves between the two surfaces.
