ShipBuilder linked a few days ago to a strange attractor program called chaoscope.I knew the existence of strange attractors before, but only as weirdmathematical objects and never realized there could be a practicalinterest for them. Well, i was wrong. When i saw the images createdwith chaoscope, i realized many of them were looking like volumetricnebulaes, a topic that i already investigated, if you remember myjournal updates, maybe a year ago.
Anyway, i quickly started to google for informations about the "maths"behind strange attractors, and it’s surprizingly simple; technically,it’s just a function that generates a cloud point, each point beind afunction of the previous point and of a parameter set. The “hard” partis to determine the parameters that will generate strange attractorsautomatically, or in our case, nice looking nebulaes ( and i’ve yet todo that, even though i have some ideas ).
Here’s the result of a few hours of playing around:
Of course, rendered in real time ( and still a bit grainy ).
