Larry,
    you could traverse all cells and use vtkCell::IntersectWithLine...

Hello, everyone,

In Vtk, we can use vtkCutter to cut a polydata with an implicit function.
Currently, the vtkPlane is the subclass of the vtkImplicitFunction, but
vtkLine is not.
If I want to use a line to cut a polydata(to get the intersection points
with the polydata), what should I do?

Any idea is greatly appreciated!
Thanks!
