Nonlinear cells/unstructured grid - cell data not copied - vtkDataSetSurfaceFilter
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
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.
