REB_Switch_FractalTiler

public REB_Switch_FractalTiler(Generic pparent)

REB_Switch_FractalTiler

public REB_Switch_FractalTiler()

Method Detail

Init

public complex Init(complex pz)

Description copied from class: Formula

Set up for a sequence of values

This function will be called at the beginning of each sequence of values (e.g. at the beginning of each fractal orbit).

Overrides:

Init in class Switch

Parameters:

pz - seed value for the sequence; for a normal fractal formula, this will be #pixel

Returns:

first value in the sequence; this corresponds to #z in a fractal formula

Iterate

public complex Iterate(complex pz)

call for each iterated point. Overrides the parent Iterate function.

Overrides:

Iterate in class Switch

Parameters:

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.

Returns:

the next value in the sequence

IsBailedOut

public boolean IsBailedOut(complex pz)

Override the default function for bailout

Overrides:

IsBailedOut in class Switch

Parameters:

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.

Returns:

true if the sequence has bailed out (i.e. should be terminated)
