[vtkusers] Extracting algorithm outputs without rendering

I'm new to VTK, and I was wondering how I could get the geometric data from
an algorithm's output without rendering anything. Say, for example I want to
do a CDT (Constrained Delaunay Triangulation) over a set of points and
constraint polylines. I make a vtkPolyData object, fill it, set is as input
and source of a vtkDelaunay2D instance, and then what?
How do I make the algorithm run without creating filter, mapper, actor,
renderer etc. ?
I just want to "see" (in code) which edges/triangles are created in the
process and have no need for visualization. OK, I need to start the pipeline
somehow, but how do I do that?
