Summary0013472: vtkContourFilter precision with vtkBoolean/ vtkPlane
DescriptionThe quality of the generated mesh dramatically changes, when the scale (size) of
the model is changed (with adapted dims and bounds of the vtkSampleFunction).
For me, this only happens in combinations of vtkPlane or vtkBox with
vtkImplicitBoolean.
Example attached.

Bug observed in 5.8 and 6.0.

added images.tbz consisting of a MetaImage-Examples of the generated ImageData.
The MetaImages can be loaded in ParaView and the behaviour can be observed there as well.

Due to the dimension that are used for the Implicit sphere radius and the value that get assigned to each grid points, we reach some precision issue which lead to a poor cell splitting.

I uploaded another example. Those two images show that the algorithm can cope very well with very large values.
The problem seems too be very large (2e+08) positive and just large (-8000) negative values. This distribution in the first examples resulted from the boolean operation.
