Please study all the examples.  You'll note that the constructor of a
VTK class is never directly used.  This is also the reason why it's
protected.  If you study the examples you'll quickly see the correct way
to instantiate a class.

This is dependent on your data.  Think about what a 3-d Gaussian looks
like.  Consider the features in your data that you would like to retain
and the noise you would like to get rid of.  Keep in mind that a
Gaussian is very close to zero at a radius of about 4 times its standard
deviation.
