[vtkusers] Surface rendering of multiple objects

[yanqiao zhu]

Thanks Christian,

I will check the differences carefully to find out what I might have
mistaken.

By the way, do you have any idea of ways to rendering single voxels. My case
is tha one of the label only corresponds to a few separate voxels, which
cannot even form a surface, while some other labels corresponds to a lot of
connected voxels. It seems for the latter ones, surface should be used for
rendering purpose. But for the former one, surface may not be a good choice.
I am trying to find ways to combine them together. Any suggestions?

Best,
Yanqiao
