The program works by generating a low resolution fractal (400 points) for a
|
|
particular range. Then the fractal is divided into quarters. The each quarter
|
|
is given a score based on the number of colours active in it. This method is
|
|
fairly effective at keeping the program focused on an active area of the
|
|
fractal, although there is much improvement to be done. There is also an
|
|
option (on by default) to select a randomly choosen quadrant than the one with
|
|
the highest score if the randomly choosen quadrant has a score that is at least
|
|
80% of the highest score. This process of selecting a quadrant is repeated a
|
|
fixed number of times (by default, 10 times). At this point, a high resolution
|
|
(in terms of floating point precision), image is created and saved to disk.
|
|
The cutoff value is very high, which is required for deep_zooms. To help avoid
|
|
endless cylces a binary tree of the hashes of all previous iterations is stored
|
|
and checked against the current iteration.
