[vtkusers] Nonlinear cells/unstructured grid - cell data not copied - vtkDataSetSurfaceFilter (vtk 4.2)

[John Platt]

Hi Users,

 

When nonlinear cells in an unstructured grid are triangulated, cell data
for the new cells is not copied. This causes access violation when
attempting to render.

 

The following edits seem to correct this problem.

 

vtkDataSetSurfaceFilter.cxx /
vtkDataSetSurfaceFilter::UnstructuredGridExecute()

 

At about line 892 insert 

 

            outputCD->CopyData( cd, cellId, this->NumberOfNewCells++ );

 

Repeat at about lines 906 & 931.

 

If this is still a problem (I don't have CVS client installed yet),
perhaps these changes could be reviewed and make vtk 4.4.

 

Thanks.

 

John Platt
