Problems with vtk3.1

[Tian-Qing Ye]

Hi Lisa

Thank you very much for the reply!

I am using the released version of vtk3.1, not nightly.

I can't compile the source if I take StructuredPoints
as input for vktImageViewer(it was ok for the vtk2.4).

Should I take the nightly released version?

Cheers

Tianqing
