[vtkusers] vtkDelaunay2D problem

[Paul Tait]

Hi

I've done this

polydataTop->SetPoints(pts);
polydataTop->GetPointData()->SetScalars(heights);
polydataTop->SetPolys(constrained);
vtkCleanPolyData *clean = vtkCleanPolyData::New();
clean->SetInput(polydataTop);
del2->SetInput(clean->GetOutput());
clean->Delete();
// del2->SetInput(polydataTop);
del2->SetSource(polydataTop);
del2->SetTolerance(0.00001);
cf->SetInput(del2->GetOutput());
cf->SetScalarModeToValue();
cf->GenerateValues(20, lpRange);

but I get the same diagnostics. Am I cleaning it right ?

Paul
