Hi,

I have two splines (identical for testing, only difference is on
different Z plane),
then I generated about 400 points each, and use VoxelContourToSurface on

these two sets of 400 points, I got :

ERROR: vtkImageData.cxx line 1190 vtkStructuresPoints: Bad Extent,
retaining previous values, Press cancel ...

Experienced vtk users, what is the implication of these?  From my
limited
understanding from readind the code and docu, it seems that there are
some ill formed triangle, is that right?  Any work around?
