[vtkusers] vtkusers Digest, Vol 151, Issue 35

[Richard Frank]

Hi,


This impacts me as well. Is there a bug filed on this? 

For display of  volume segmentation, it would seem that the mask feature
would be the thing to use. I couldn't get it to work, and wasn't sure if it
was a bug or just my missing something.

Thanks

Rick
