You probably took an example for Delaunay2D (which would compile as-is),
but there is a fondamental difference. See the man pages:

"vtkDelaunay2D is a filter that constructs a 2D Delaunay triangulation
from a list of input points... The output of the filter is a polygonal
dataset."

"vtkDelaunay3D is a filter that constructs a 3D Delaunay triangulation
from a list of input points... The output of the filter is an
unstructured grid dataset."

That explains why you cannot compile the line above. See an example for
Delaunay3D to insert a Filter between your two objects (for example
vtkShrinkFilter).
