AbstractWritableSuperEllipsoid

public AbstractWritableSuperEllipsoid(double[] center,
                                      double[] semiAxisLengths,
                                      double exponent)

Creates an n-d superellipsoid, where n is determined by the length of the smaller array.

Parameters:

center - position of the superellipsoid in space, given in pixel coordinates

semiAxisLengths - array containing n elements representing half values of width/height/depth/...

exponent - exponent of the superellipsoid
