[vtkusers] Select Visible Nodes in 3D -- any vtkSelectVisiblePoints for 3D ???

[Davood Ansari]

Hi all

I am visualizing a high order FEM grid.
For now I can visualize the whole mesh and it's auxilary nodes in 3D.
As you may guess it is a pretty messy view. Now I wonder if there is any
tool
by which I can confine the visualization to a certain box region of the
mesh.
In 2D we have the vtkSelectVisiblePoints but I could not find a 3D
equivalent
for it!!

Please comment

Thanks
Davood
