0037 //! This  class processes the  data  resulting from
0038 //! Blend_CSWalking  but  it  takes  in  consideration the Surface
0039 //! supporting  the  curve to detect the  breakpoint.
0040 //!
0041 //! As  a  result, the  criteria of distribution of
0042 //! points on  the line become  more flexible  because  it
0043 //! should  calculate values  approached
0044 //! by an approximation of continued  functions based on the
0045 //! Blend_RstRstFunction.
0046 //!
0047 //! Thus this pseudo path necessitates 3 criteria  of
0048 //! regrouping :
0049 //!
0050 //! 1) exit of  the domain of  the  curve
0051 //!
0052 //! 2) exit of  the domain of  the surface
0053 //!
0054 //! 3) stall as there  is a solution of problem
0055 //! surf/surf  within the domain  of the  surface
0056 //! of support of the restriction.
0057 //!
0058 //! Construction of a BRepBlend_Line between two pcurves
0059 //! from an approached starting solution. The output
0060 //! entries of this builder are of the same nature
0061 //! as of a traditional walking, but the requirements
0062 //! to the Line are not the same. If the determination of validity range is always
0063 //! guaranteed, the criteria of correct repartition of sections
0064 //! before smoothing are not respected. The resulting Line
0065 //! is f(t) oriented.
