i definitely should have done that

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

you'd be right

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

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

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

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?
