04:40 <InPhase> teepee: Does the Qt Designer do a good job of making diff changes be actual changes?

04:41 <InPhase> teepee: I haven't touched it in ages, because this did not used to be the case.

04:41 <InPhase> "change name of button" --> 1000 lines have been updated.

04:42 <InPhase> Maybe modern source code management was figured out by them somewhere along the way. :)

04:47 <J25k93> guso78 you don't get a gimbal lock with quaternions

04:49 <InPhase> J25k93: Yeah, you can turn all 720 degrees around in any direction without any problems. :)

17:46 <pmn_> how do i *plot* a mathematical function?

17:47 <pmn_> i'm trying to create a CRT casing plus sunshades (one object) with Gompertz curve or generalised logistic function

17:47 <pmn_> it's for casing a display panel and housing the eDP driver for it

17:49 <pmn_> in my head, i had it that i would draw out the curve in [-y1, y1] with start of the growth at some -x1 for some positive x1

17:50 <pmn_> then, linear_extrude() that^ and get the vaccume tube you see here: https://www.makingsoftware.com/ (scroll down a bit)

17:51 <pmn_> it could be done with decay function too but again i don't see anyway to do this from the manual or the cheatsheet

17:52 <pmn_> i have seen something close to it here: https://github.com/whosawhatsis/Calculus/tree/main/exponentials

17:53 <pmn_> but not exactly the same thing...

17:53 <pmn_> any help?

18:12 <teepee> pmn: feeding the function into a polygon is relatively easy

18:17 <teepee> https://pastebin.com/8pmeEQ87

18:26 <pmn> teepee: i see

18:54 <pmn> oh wow. that's simple: https://pastebin.com/apN384SC

18:59 <pmn> problem there is it's as if it's taking the antiderivative of that function; i don't want the area between x and f(x)

19:00 <pmn> once i call the linear_extrude() on this polygon it's going to be a filled solid object; then i have to fix it with difference()? i don't know how to do that...

19:00 <pmn> oh, another polygon with smaller scales i guess

19:29 <teepee> it also depends on how this is processed further, in some cases a solid object is fine leaving the shell operation to later steps

20:21 <kintel> Preview or render multiple times during a test case run: This was discussed a loong time ago, but I wonder if it's convenient to bring it up again: It would be very helpful to be able to preview or render a design multiple times in succession (i.e. without restarting the process) during testing, and extract some metadata. I'm thinking about more convenient ways of testing things like caching, VBO generation vs. rendering, perhaps animation, and any

20:21 <kintel> other feature where the second rendering may behave differently from the first.

20:22 <kintel> Did anyone happen to think about this recently? :)

20:33 <teepee> I have not
