One way is to use explicit surface reconstruction. Pass your points into
vtkSurfaceReconstructionFilter and the output through vtkMarchingCubes. The
default parameters should work fine for both.

Will only work if the points are densely sampled on the surface, also has
problems with incomplete surfaces.

Hope this helps,

Tim.
