CollapseSingularities()¶ - Preprocess surface to be offset (bspline, bezier, or revolution based on bspline or bezier curve), by collapsing each singular side to single point. //! This is to avoid possible flipping of normal at the singularity of the surface due to non-zero distance between the poles that logically should be in one point (singularity). The (parametric) side of the surface is considered to be singularity if face has degenerated edge whose vertex encompasses (by its tolerance) all points on that side, or if all poles defining that side fit into sphere with radius thePrecision. //! Returns either original surface or its modified copy (if some poles have been moved).

Surface()¶ - returns the Offset surface computed from the surface <Surface> at an OffsetDistance <Offset>. //! If possible, this method returns the real type of the surface ( e.g. An Offset of a plane is a plane). //! If no particular case is detected, the returned surface will have the Type Geom_OffsetSurface. Parameter allowC0 is then passed as last argument to constructor of Geom_OffsetSurface.
