Hello.
I've been looking at FAQ's all over the net and I cannot get a
decent plasma cloud algorithm. FAQs are getting old, links to programs
their refer to are gone. And all I could get was that you start from
the four corners on a image, pick random colors for each of them and
recurse. This isn't very clear to me as to how the magic happens.
Say my square goes from (0,0) to (1024, 1024). In the next step, my
target square is now (0,0) - (512,512). What do I do with the color
already assigned at (0,0) ? Pick up a new color and average it with the
new ? This tends to produce darker colors at each iteration. Do I need
to take into account the surrounding pixels? At this point of my
algorithm,(0,1) is unassigned(or has a default black or white pixel).
When will (0,0) take into account it's neighbors to make it seemless
since (0,1) can be anything at this point?
I am missing the logic of this. Any help or link to existing
(and current) tutorials will be greatly appreciated.
Thank you.
