Dear VTK Users,

would you explain to me how to use the method 'IntersectWithLine()' of the class vtkCellLocator.
There are three versions of this method. The first one is:

virtual vtkCellLocator::IntersectWithLine(double a0[3], 
                                                          double a1[3],
                                                          double toi,
                                                          double& t,
                                                          double x[3],
                                                          double pcoords[3],
                                                          int& subid)


In the html-doc there is no explanation of the parameters of the method, so I don't know how to call it.
I have a vtkPolyData object and two points in 3D which define the line. And I want to check whether the line intersects the vtkPolyData object.

Do you have any ideas?
Thanks!
