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. + +WWW: http://members.rogers.com/rowley-c/deep_zoom/ |
