Provides various methods with Geom2d and Geom curves and surfaces. The methods of this class compute the parameter(s) of a given point on a curve or a surface. The point must be located either on the curve (surface) itself or relatively to the latter at a distance less than the tolerance value. Return FALSE if the point is beyond the tolerance limit or if computation fails. Max Tolerance value is currently limited to 1.e-4 for geometrical curves and 1.e-3 for BSpline, Bezier and other parametrical curves. More...
