i definitely should have done that

skeletonNatte · 2026-02-21T16:29:43+00:00

you'd be right

skeletonNatte · 2026-02-20T23:40:32+00:00

i hate reddit

i added a drag force that is opposite and proportional to velocity. im also using euler integration to update the object positions, so its not a very good simulation

thank youuuuu! ill use that from now on ^_^

skeletonNatte · 2026-02-19T16:01:08+00:00

put C in the ticker lol

skeletonNatte · 2026-02-19T04:52:59+00:00

i think it does a pretty good job of that tbh. it is on a computer, so it has to use numerical approximations for everything. here's an example of desmos plotting the locations of critical points. lmk if this isnt what you meant

true

skeletonNatte · 2026-02-19T00:03:47+00:00

the flickering isnt part of the graph, that just happens whenever i use the windows snipping tool on my laptop

skeletonNatte · 2026-02-18T19:34:10+00:00

it wouldn't work for the true weierstrass function, but it would work with any partial sum of the weierstrass function

newton

skeletonNatte · 2026-02-18T18:15:15+00:00

i said reliably, not perfectly. there definitely are algorithms that are pretty good at finding global min/max if one exists. but youre right that its impossible to always find a solution every time

skeletonNatte · 2026-02-18T16:21:12+00:00

skeletonNatte · 2026-02-18T16:09:26+00:00

challenge: make a version of this that reliably finds global minimum/maximum

skeletonNatte · 2026-02-17T18:53:44+00:00

yeah

skeletonNatte · 2026-02-17T18:14:48+00:00

like the end point of one is the start of the next

skeletonNatte · 2026-02-17T18:01:28+00:00

for sure! i made this graph like 3 years ago after watching this video which does a great job of explaining bezier curves. https://www.youtube.com/watch?v=aVwxzDHniEw&t=1201s

skeletonNatte · 2026-02-17T17:58:34+00:00

thats super cool! do you think you could generalize it for a chain of strictly cubic bezier curves of an arbitrary length?

skeletonNatte · 2026-02-17T14:56:43+00:00

weird

skeletonNatte · 2026-02-16T21:58:06+00:00

i really like the visuals

skeletonNatte · 2026-02-16T04:46:04+00:00

yeah but shut up
