44//! Computes the intersection between a face and a
45//! curve. To intersect one curve with shape method
46//! Init(Shape, curve, tTol) should be used. To
47//! intersect a few curves with specified shape it is
48//! necessary to load shape one time using method
49//! Load(shape, tol) and find intersection points for
50//! each curve using method Init(curve). For
51//! iteration by intersection points method More() and
52//! Next() should be used.
53//!
54//! Example:
55//! Inter.Load(shape, tol);
56//! for( i =1; i <= nbCurves;i++)
57//! {
58//! Inter.Init(curve);
59//! for( ;Inter.More(); Inter.Next())
60//! {
61//! .......
62//! }
63//! }
