//I've removed this smoothing because it doesn't really make sense to apply a low pass filter to a volume with material values.
//I could implement the mathematical operators for MaterialDensityPair in such a way that they ignores the materials but this
//seems to be setting a bad example. Users can add this operators in their own classes if they want smoothing.
