[vtk-developers] vtkPointCloud remote module

[Bill Lorensen]

Will,

To build as a remote module, users should place the attached file in
vtk_source_directory/Remote

Then
1) cd vtk_build_directory
2) cmake -DModule_vtkPointCloud:BOOL=ON ../VTK
2) make


I just tried it and it built great on my mac. It is missing a baseline image.
