[vtkusers] Identifying the difference between two objects

[Cory Quammen]

You might be interested in this paper that introduces a technique for
comparing two objects:

http://www.cs.unc.edu/~weigle/Papers/Vis05-Intersecting_Surfaces.pdf

A version of the technique where you view the union of the surfaces in
wireframe (or semi-transparent, though that isn't great for understanding
shape) and the intersection of the surfaces as solid is fairly easy to
achieve with the boolean operation filter:

http://www.vtk.org/doc/nightly/html/classvtkBooleanOperationPolyDataFilter.html

The code in this filter is based on the code developed to generate results
for the paper I cited above.

An example of using the boolean operation filter is available at:
