> As shown above, the data set is two cubes and they share the same surface.
> I made a vtkMultiBlockDataSet like this:
>
> along x dir, 4 lines, each line I set it to be a block;
> along y dir, 6 lines, each line I set it to be a block;
> along z dir, 6 lines, each line I set it to be a block.

> Then just as normal, set up renderWindow, renderer, actor etc. Note: I did
> add macros in vtk 6.0, and FYI, I did successfully show up another
> vtkMultiBlockDataSet, i.e., 2 cubes, but they don't share any surface.

> So, my question is : Why it shows up in vtk 5.7 but not in vtk 6.0? Is it
> possible somehow vtk 6.0 does not support this kind of vtkMultiBlockDataSet
> (i.e., have shared surfaces, points) rendering ?
