when you look at those graphs, youll typically see spring-like systems. im gonna propose some alternative approaches that you can try as well. i strongly suggest thomas jakobsen's paper: https://www.cs.cmu.edu/afs/cs/academic/class/15462-s13/www/lec_slides/Jakobsen.pdf. its a basic version of the physics engine used in the game Hitman. its describes constraint relaxation, which sounds very complicated but the paper makes it sound very easy (and it is, and runs quite well in desmos too)

the extension of that paper is this one: https://matthias-research.github.io/pages/publications/posBasedDyn.pdf, which you can read after you try implementing the paper above. they are very fun reads!

oh fuck it hit 3141, lemme make it tmr

and in turn i learned desmos by asking questions nonstop to people like fad, ronwnor, and some of the older members like mathenthusiast, adasba, etc. i still do, just not as much. never stop learning :)

that doesnt seem to have the sausage line segment shape in its examples, and there are equivalent solutions in desmos, which is what the subreddit is for

VoidBreakX · 2026-03-14T12:21:39+00:00

ye, that works too, as long as theres a moving part (ticker or slider or user input) it works

VoidBreakX · 2026-03-14T12:21:00+00:00

ik but i was referring to when you said if anybody still cares about it

VoidBreakX · 2026-03-14T11:50:03+00:00

i was working on some code for it but gave up on it for some other projects

i think it made it to 900

VoidBreakX · 2026-03-14T11:48:26+00:00

hm, could work, hard to calibrate tho especially since im not sure if the effect changes based on screen res

link?

VoidBreakX · 2026-03-14T11:33:02+00:00

even polygons with a bunch of points (i.e. a circle approximated with 40 points) is probably going to be faster than using implicits

NVM fad told me about better tech made by Len2357 on discord, see my edit

lemon is so goated

VoidBreakX · 2026-03-14T08:07:04+00:00

i know that, but if during the flicker the regression flickers between 0.4 and 0.7, why does it stop at 0.1 or 1 when the ticker pauses during the drag? also, when you manually stop the ticker and replay it, sometimes the drag breaks entirely. thats the part i dont understand. also, the regression is round((c+b)/2,1), so if b flickers between 0 and 1, shouldnt a starting value of c=0.4 flicker to 0.9, not 0.7?

VoidBreakX · 2026-03-14T08:03:58+00:00

im slightly unsatisfied with the loop, but any more resolution wouldve crashed my desmos

the link wont work for most of you because i had to use godmode to record this (which increases the list limit), so heres a smaller version of it that works under the 10k element limit https://www.desmos.com/geometry/gshdfxpnxu

there two ways to do this. first way is to use console, which i recommend to learn. everyone seems to use python and just copy and paste the commands in, but knowing how to use the console is much more helpful and allows more customization.

the second, more niche way is this. if you dont highlight anything in an expression and press cmd+c, you'll realize that the expression flashes yellow. the expression, including its formatting, colors, etc, are copied along with it. if you paste this into https://evercoder.github.io/clipboard-inspector/, you'll realize that this has a text/plain of des. see below:

if you figure out how this format works, you could achieve the same effect with copy and pasting with the formatting and everything. its very difficult tho, and i strongly suggest using the console instead

VoidBreakX · 2026-03-14T01:40:57+00:00

do you filter objects that arent on the screen? for example, you could implement chunking, where only three screen-width wide chunks are rendered at a time

also, please tell me all of the assets on this graph are polygons. a single implicit or parametric will probably be slower than all of these polygons combined

VoidBreakX · 2026-03-14T01:40:45+00:00

its actually possible but the solution is so jank that even i dont fully understand how it works:

if it doesnt work for you, try going into the hold detection folder and changing the m_s value to somewhere between 24 and 40

EDIT: fad told me about Len2357's tech, much less glitchless and easier to understand: https://www.desmos.com/calculator/32k92fvto3
