<Guest70> So. What are the devs working on? The number of releases have slowed considerably theses days. Aside from betas, no release since 2021 ...

* teepee can't see any slowdown ;-)
<Scopeuk> Guest70 the Dev team is pretty much three volunteers. There is a current plan to work towards a new release to get manifold (the new faster geometry engine) into the release version but due to limited resource and the project needing all the pastoral stuff doing it's not hugely fast
<Scopeuk> teepee also makes a fair point, releases have always been infrequent :p
<Scopeuk> Also Guest70 thanks for sticking arround to get an answer, so few people do
<teepee> not saying I like it, but 2015, 2019, 2021, 2025 (maybe?) seems almost consistent :)
<J25K> 21 was bit rushed ..

<Joel> first time with polyhedron's.... I think I'm going to end up hating openscad lol
<J25K> deleted all the anchors and restructured everything
<J25K> Joel we have some good examples
<J25K> and there are some lib with tools to show points and faces
<Joel> yeah, we'll see how stuck i get
<Joel> It's a complex shape that makes me miss sketchup, I really should learn some other point and click based modeling tool one of these days
<gbruno> [github] amatulic edited issue #6075 (Every link in the cheat sheet is now broken) https://github.com/openscad/openscad/issues/6075
<teepee> using a library can help massively, and there are also small special focus libraries
<J25K> https://en.wikibooks.org/wiki/User_talk:VulcanWikiEdit  .. well lets see how that play out
<teepee> yeah, that's why I also linked the issue above ^
<J25K> if we can't protect certain areas of the pages and nobody notice that amount of changes ..
<J25K> and we have no bot to check and warn
<teepee> you can register for page changes. I don't know if there's some sort of bulk subscribe though
<J25K> if you see how much that user changed ..  i first thought it is some AI bot
<J25K> do we have an unaffected offline version of the cheatsheet with linked content?
<teepee> no, but I think wikipedia has a versioned download for all the stuff, wikibooks might have something similar
<teepee> let me check that actually
<teepee> "All pages with complete edit history (.7z)": 1.2GB
<teepee> heh, good thing I just bought another 16gb raspi as additional server ;-)
<J25K> So at least we could make a history version of the cheatsheet  by linking to the history
<teepee> hmm, not so good part: "404 file not found"
<J25K> our backup..
<teepee> ah, no, file is there, just the index page is wrong
<teepee> uff, what? 30.8mb/s download? I did not know that was possible :D
<J25K> if a single person changes so much - someone need to read through all those
L29Ah has left #openscad [#openscad]
<teepee> there was quite some discussion everywhere, like here, on the mailing list and in some github issue
<J25K> and from what i have seen this was restructured so parts are removed without knowing were they are now or if
<J25K> well i am surprised nobody noticed the broken links
<J25K> but if the wiki is good .. should be easy to repair the links
<teepee> ouchies, that's actually a single ~100GB XML file
L29Ah has joined #openscad
<J25K> wow XML can get that big - what editor can read a 100GB file
<teepee> I guess the first step would be filtering out just the openscad stuff, that should trim it down quite a bit
<J25K> I just asked an AI .. and suprisingly it works better than any wiki for a user to get help on a topic
<teepee> depends on how you ask and how much it was trained on. I guess the really big models have half the internet in there :)
<teepee> problem is you can't really rely on the results
<J25K> and you can't change them ..
<J25K> however it would be probably easy to create a new linked version like https://imgur.com/a/oC22LYd
<teepee> yeah, someone generated a similar one on the mailing list some time ago
<teepee> looks not too bad as a reminder and reference, but the benefit of the cheatsheet is also that it links into the full docs
L29Ah has left #openscad [Error from remote client]
<J25K> linked ..
L29Ah has joined #openscad
<teepee> it still links there ;-)
<teepee> just not the correct places
<teepee> hmm, transforming the 100gb xml to json to run it through a json parser seems silly...
<Joel> the ordering piece of the polyhedron is very confusing, does it really matter order if you're consistent in both points and faces?
<teepee> the ordering of points of each face must be correct as that give the information of what's inside and what's outside
<teepee> if you switch view to "thrown-together" the inside is pinkish color
<Joel> "the ordering of points of each face must be correct" what's correct?
<teepee> once you finish the polyhedron there should be no such colored face anymore
<teepee> I just try it and flip the direction if the pink color shows up on the wrong side :)
<teepee> the docs have the specification... somewhere... still...
<Joel> I mean, that's what I was asking about
<teepee> "In the list of faces, for each face it is arbitrary which point you start with, but the points of the face (referenced by the index into the list of points) must be ordered in clockwise direction when looking at each face from outside inward. The back is viewed from the back, the bottom from the bottom, etc. "
<Joel> "outside inward" anyone care to dumb that down for me?
<teepee> you have a cube
<teepee> you are NOT sitting inside the cube but looking at the face from outside
<Joel> that I get
<teepee> the vertices of that face need to be clockwise
<Joel> when you adjust y, do you just keep going clockwise? I had a 2d object drawing?
<Joel> or do you do each point in y, then rotate?
<Joel> s/had/have/
<teepee> I don't understand what that means. rotate what?
<Joel> it's also funny because the cube example in doc is counter clockwise
<Joel> unless clocks are flipped in the southern hemisphere
<teepee> yes, the top and bottom have different winding order when looking from the same direction
<teepee> because on the front you look at the outside, on the back you look at the inside of the face
<Joel> I apparently missed whatever math class makes this make sense
<Joel> https://gist.github.com/jjshoe/303bb1ef2cab213f8c789fee94124a3c - trying to figure out how to make it thicker now essentially
L29Ah has left #openscad [#openscad]
<Joel> on the Y access
<Joel> err Z *facepalm*
L29Ah has joined #openscad
<teepee> which one?
<Joel> Z
<teepee> I mean in the gist?
<Joel> The one labeled "Renders" works, I think, that's what I'm trying to get to grow on Z, doesnt is my failed attempt
<Joel> Of course, I think I'm confused, because the one labeled "renders" works when I hit f5, but not f6, preview vs render, grrrr
<teepee> it's just same thickness everywhere?
<Joel> yes, just 1/8"
<teepee> then I'd suggest using linear_extrude() polygon() instead
<Joel> I think I'll probably just switch to a different tool for this project
<teepee> linear_extrude(5) polygon([ [0, 0], [0, (3 + 1/8) * mm], [(1 + 3/4) * mm, (3 + 1/8) * mm], [(1 + 3/4) * mm, (3 + 1/8) * mm - (1 + 1/2) * mm] ]);
<teepee> polygon just in Z = 0
<teepee> linear_extrude(5) makes it 5 units thick
