Detailed Description

Complements standard tool Geom_Surface by providing additional functionality for detection surface singularities, checking spatial surface closure and computing projections of 3D points onto a surface.

The singularities Each singularity stores the precision with which corresponding surface iso-line is considered as degenerated. The number of singularities is determined by specifying precision and always not greater than 4.
The spatial closure The check for spatial closure is performed with given precision (default value is Precision::Confusion). If Geom_Surface says that the surface is closed, this class also says this. Otherwise additional analysis is performed.
The parameters of 3D point on the surface The projection of the point is performed with given precision. This class tries to find a solution taking into account possible singularities. Additional method for searching the solution from already built one is also provided.

This tool is optimised: computes most information only once

periodic B-Splines are closed,
polinomial B-Spline with boundary multiplicities degree+1 and Bezier - maximum distance between poles,

◆ ProjectDegenerated() [1/2]

Then sets not yet computed <result>'s coordinate taking it from <neighbour> and returns True.

◆ ProjectDegenerated() [2/2]
