[vtkusers] Cut a triangulated surface with a line

[Martin Vymazal]

Hello,

 I would like to ask if  I can slice elements in triangulation. Suppose my 
input is a line on a triangulated surface (given as a sequence of vertex pairs 
indicating which mesh edges the line should cut, for example), I would like to 
split the triangles that the line passes through, eventually introducing new 
triangles in the mesh. Apparently there is the class vtkCutter, but I'm not 
sure that that's what should be used. Could you please point me to some 
examples if there are any? How should I feed my input line to vtk? Create a 
polyline perhaps?

Thank you very much,

 Martin Vymazal
