[vtkusers] Line intersect with 2D cells

[yujie_job at 163.com]

Hi, all!
I wish there is someone can solve my problem.

Is there any class or way in vtk to get intersect points and cell Id for
line intersect with 2D cells? I have post a draft to explane what I want to
say. the red line and quadric cells are in the same plane(such as z=0), now
I want to get the intersect points and cell ids whick are intersected with
red line and cells.

I have tried function in intersectWithLine in vtkOBBTree, but it works for
3D cells intersect with line. Is there any way to solve this prolem for 2D
cells?

thanks for your view and help!
