[[[[request existed to implement pure particle system by hand without references [for fun], i didn't simulate water well as a child and i know much more now, especially after reading that. ummmm but i'm not very good at ummm graphic things any more. very very emotionally blocked. ascii graphics are even quite hard >_> <_< could quickly destabilize. <_< <_< ummmm so maybe i'll poke at some numbers ... i might make a very simple simulation without rendering anything :s :s :s
it's fun to try :D
basically i know very little about this and it's really interesting to learn because i repeatedly tried to figure it out as my own when young!
and now we have tensors and can operate on thousands and thousands of points in parallel
basically i would try to figure out some kind of constant volume using [uhhhhhhhhh uhhhhhh the principle that the newton toy is based on, where hitting an object on one end makes one bounce on the other [which would basically mean deriving something simple on my own :D very slowly :D
uhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh and if i made some numbers maybe somebody else, while i covered my eyes and turned away, could try running it and see what it looked like, who knows?
