One thing is surprising on this picture:

all the vertices on a "line" of the mesh should have the same  
computed differential quantities, cause the mesh is regular and the  
patches symmetric, so the estimations are only done on translates. So  
i think there may be a bug in the way neighbors are retrieved, you  
may want to check and compare the patches for vertices along the same  
"line". Note that if this is the problem, it is only related to the  
example code and not the core of the package.
