Mr. Lorensen, thank you for the response.

The documentation is a little bit terse about the underlying algorithm of
the vtkContourFilter. I was able to confirm it is indeed marching triangles
from this course note:
http://www.inf.ed.ac.uk/teaching/courses/vis/lecture_notes/lecture7.pdf

And from a commented line in the source code:
http://vtk.sourcearchive.com/documentation/5.0.4/vtkTriangle_8cxx-source.html

Nevertheless, thank you for the response.
