[vtk-developers] vtkPointCloud remote module

[Will Schroeder]

I've actually got several baseline images to push in. I'll try and do this
tonight when I have more time.

BTW thanks for your help Bill, the remote module stuff you added is very
nice and I see there are some nice modules starting to appear like DICOM
(David Gobbi ?), Poisson reconstruction and some Slicer code.

Best,
W
