[vtkusers] Why vtkDelaunay2D cannot generate Cell

[qin zeng]

Hi, all,

I have a polydata pass through vtkDelaunay2D

After that I use vtkDelaunay2DGetOutput()->GetNumberOfCells() to query the number of cells.

The number is 0   which will cause the error of "no data to contour" when vtkContourFilter applied.

Why??
