01:00 <kintel> Does anyone have a good CMake pattern for when two libraries use the same submodule?

01:00 <kintel> Context: I want to add Clipper2 as a submodule, and Manifold already adds it as a submodule

01:00 <kintel> modulo when Manifold and/or Clipper is externally built

01:01 <kintel> ..but both libraries are in active development and we may need a submodule for some platforms

01:09 <InPhase> J24k48: I have no horse in the race of ordering, but put mine in place where I did as nothing else was there when I did.

01:10 <InPhase> J24k48: Although I made no attempt to explain rotate_extrude in depth, but just sort of dropped it there as assumed background.

01:11 <InPhase> I was kind of taking the advent calendar tutorialling as not necessarily striving to be comprehensive or a replacement for the main tutorial, but just sort of a supplemental introductory method to broaden people's background.

01:15 <InPhase> And perhaps with it mixed amidst the other designs, it's okay for unexplained teasers of features to be used and then perhaps later explained more meticulously. Like Day 1's tree actually uses the same sort of equation approach for its shape that I explained in tutorial 7.

01:16 <InPhase> (That was actually my motive for what to try to explain in that tutorial.)

01:17 <InPhase> Mysteries unwrapped like presents? :)

01:17 <InPhase> (Or just bad pedagogy... lol)

06:41 <JordanBrown1> teepee no link to 2024 calendar on openscad.org/gallery

08:51 <J24k38> InPhase - i thought we could add the scadvent tutorial to the examples - so scad would come with tutorial

12:26 <InPhase> J24k38: An interesting proposal. That makes sense too.

12:27 <InPhase> J24k38: Let me put forward that any elements that are deemed "flaws" from rushing during calendar time could also be fixed up for that purpose too.

12:28 <J24k38> yes - and updated .. but would be nice to have for a future release

12:30 <InPhase> I think I'd still probably point people toward the other tutorial first, just because so much more thought was put into the ordered arrangement of that. But I like the idea of integrated tutorial examples in the release. And these examples are showing different aspects in different ways.

12:34 <InPhase> Impressively the rate of people coming back after being sent to the current web tutorial and saying they don't understand something covered in it is very near to zero. I can't remember a case of that happening once, which is impressive. Although it is also not a complete coverage of everything that could be taught. :)

17:52 <aquila> Hello everyone. I am interested in contributing to VLC or VLMC using C++. I have a fair bit of knowledge of OpenGL. If someone could point me to simple issues / projects I could get started with

18:13 <teepee> aquila: sounds like you misclicked the channel :-)

18:17 <teepee> hmm, there is #vlc but it has only 9 people, so it might not be the main place

18:17 <Friithian> Id assume vlc has an active chat somewhere

18:18 <Friithian> #videolan seems to be the official channel

18:18 <Friithian> aquila: https://www.videolan.org/support/

18:18 <teepee> yeah website points to #videolan

18:19 <teepee> 220 people

18:21 <aquila> oops, i had vlc chat open too

18:21 <teepee> no problem, vlc is awesome and the people with their vlc hats are fun :)

18:21 <aquila> i had joined, since i was curious about contributing to brlcad / openscad in graphics

18:22 <aquila> and where i could start out, preferrably related in c++/opengl

18:22 <teepee> yep, openscad uses that too

18:23 <teepee> no vulkan in sight yet

18:23 <Friithian> damn, opengl ur a beast

18:23 <teepee> yeah, we even have some old style stuff that really really should be retired and replaced

18:23 <InPhase> teepee: Didn't we at one point have a prettier-rendering opengl proposal in the suggested GSoC list?

18:24 <InPhase> Is that still there?

18:24 <teepee> yes, extended shader support

18:24 <teepee> there's even some pull request, but I think it needs some more work

18:25 <teepee> it might be superseeded by the work kintel did a while ago for supporting newer contexts

19:00 <InPhase> aquila: So there do appear to be some important outstanding needs we can point you to. If you have a serious interest in working in this area, the two best pieces of advice I can give starting out, are to stick around here in the channel for a while, for a place to discuss work and get early feedback to make sure work will end up merged, and second, to start out by going into the source and

19:00 <InPhase> familiarizing yourself with the places where opengl integration occurs. Checking the current state of the master branch shader code and integration is a good start. Then you would be prepared to look over the pull request teepee mentioned to compare.

22:08 <guso78k> Reading the openscad source code, i understand, that every module instantiation also got an else scope, but i did neither see SCAD code using that, nor any hint in the chear sheet.

22:08 <guso78k> could anybody give me an example ?

22:45 <teepee> Extrusion: https://github.com/openscad/openscad-advent-calendar-2024/blob/main/TutorialPart08/TutorialPart08.scad

22:45 <teepee> Modules: https://github.com/openscad/openscad-advent-calendar-2024/blob/main/TutorialPart09/TutorialPart09.scad

22:51 <J24k> sehr schön

22:52 <J24k> but did you already had for loops? as they are used in part9 ?

22:56 <teepee> sort-of, not for modules

22:57 <teepee> they get an extra mention in the comments though :)
