The SimpleDoublePrecisionJuliaGenerator provides an implementation for
calculating the number of required iterations to determine the divergence of
the sequence of points obtained by the recursion
zn + 1 = (zn)2 + c
where c is the point passed to the setDefiningPoint method and is constant
during the calculation of the fractal and z1 is a point
determined by screen coordinates.
The SimpleDoublePrecisionMandelbrotGenerator provides an implementation for
calculating the number of required iterations to determine the divergence of
the sequence of points obtained by the recursion
z1 := 1, zn + 1 = (zn)2 + c
where c is a point determined by screen coordinates.
