Description

Given a NURBS curve handle and a point (in world space), this function returns the parameter of the point obtained by projecting the input point. The function also returns the index of the piece in the piecewise NURBS curve on which the projected point lies.

FUNCTION GetParameterOnNurbsCurve(
                  h                      :HANDLE;
                  pointX,pointY,pointZ   :REAL;
                  VAR parameter          :REAL;
                  VAR index              :LONGINT) : BOOLEAN;

def vs.GetParameterOnNurbsCurve(h, point):
    return (BOOLEAN, parameter, index)

Parameters

h		HANDLE
point		REAL
parameter		REAL
