Object version of the MMF Formula Wars 2 formula
Extended to allow the combination of up to 6 formulae
Note that for historical reasons this formula uses its own
zold and bailout values instead of those defined in the base class
doing so should not be taken as a model for other formulas.

Method Detail |
---|
public complex Init(complex pz)
MMF_SwitchConvergentDivergentFormula
What it's initialised to is normally irrelevant unless the derived
formula uses zold in its main calculations in which case the user
should be given the choice of initialising zold to either the location,
the initial z value or a fixed constant.
Init
in class MMF_SwitchConvergentDivergentFormula
pz
- the location (normally #pixel)
public void SetParams(boolean f, complex v)
SetParams
in class MMF_SwitchConvergentDivergentFormula
f
- flag for Mandelbrot or Julia mode, is true for Mandelbrotsv
- the value to be used as the start value or constantpublic complex Iterate(complex pz)
ConvergentDivergentFormula
As long as the sequence has not bailed out, this function will be continually called to produce sequence values.
Iterate
in class ConvergentDivergentFormula
pz
- previous value in the sequence; corresponds to #z in a fractal formula. Note that you should always use this value for computing the next iteration, rather than a saved value, as the calling code may modify the returned value before passing it back to the next Iterate() call.
public boolean IsBailedOut(complex pz)
ConvergentDivergentFormula
Since this is a divergent fractal, the test is easy: if it's bigger than the bailout, the sequence is done.
IsBailedOut
in class ConvergentDivergentFormula
pz
- last sequence value to test; this should be the value returned from the previous Iterate() call. Note that it is acceptable to ignore pz and use m_BailedOut, but any code calling IsBailedOut() should pass in the correct pz for Formula classes which do not use m_BailedOut.
