00:19 <kintel> Church- Slightly OT: Any must-do things in Riga for an OpenSCAD developer? Planning a trip..

01:12 <InPhase> Is it not just a Riga-ler city?

02:13 <kintel> No no, I hear their tRiganametry is amazing!

11:30 <Church-> kintel: i'm completely newbie in openscad, just unix sysad, that wanted some 3d printed gizmo for his simrace rig .. and somehow ended up customizing one of found models from thingiverse .. so .. completely no clue, what openscad related might be here in this city ..

11:30 <Church-> otherwise, for generic tourism, Riga just one of many normal/but not overly special cities to visit. Some good stuff, some old buildings in centre in "old-Riga", some atractions .. for someone living here it all seems "nothing special" :)

17:51 <gunnbr> status?

17:51 <othx> Gthx.NET version 2.26 2022-12-28: OK; Up for 33 seconds; mood: pretty good.

17:51 <gunnbr> YAY!!!!! It lives!!

17:53 <gunnbr> android?

17:53 <othx> android is http://www.scorchworks.com/ScorchCAD/scorchcad.html

17:54 <gunnbr> Is even using the correct DB!

17:54 <gunnbr> Sorry for all the downtime! Stupid user errors during an upgrade.

17:57 <peeps[zen]> botsnack!

17:57 <othx> YUM! This is why I love #openscad.

17:57 <peeps[zen]> botmaintainersnack!

17:58 <peeps[zen]> thanks gunnbr :D

18:02 <gunnbr> You're welcome!

18:28 <guso78[m]> Scorchcad exists for a Long Time. I regularily use IT in vacation

18:33 <guso78> https://imgpile.com/i/9sslxr thank you, OpenSCAD !

18:41 <juri_> implicitcad?

18:41 <othx> implicitcad is a different approch for implementing CSG based cad (http://www.implicitcad.org/) based on manipulating implicit functions (http://christopherolah.wordpress.com/2011/11/06/manipulation-of-implicit-functions-with-an-eye-on-cad/). For some discussion see the mailing list post at http://forum.openscad.org/ImplicitCAD-0-0-1-td2544.html

18:41 <juri_> :D

18:41 <juri_> hslice?

18:42 <juri_> hmm. must be an older database.

18:44 <guso78[m]> No this was designed with openscad

18:47 <teepee> scorchcad is abandoned

18:53 <teepee> hmm, actually I can't find that article anymore, so maybe it's still alive?

18:54 <teepee> ah, there it is https://twitter.com/shamus_carter/status/1346968909514223624

18:55 <gunnbr> As far as I know, this is the most recent DB. Looks like it was running up until February when I foolishly upgraded the server.

18:56 <teepee> juri_: it's not the same db as in #reprap, so maybe the entry you expect is in that one?

19:08 <guso78> gunnbr you are a bot ?

19:09 <gunnbr> I don't think so.

19:09 <gunnbr> But how would we ever know?

19:09 <gunnbr> I could be ChatGPT.

19:09 <guso78> haha

19:09 <guso78> or a relay to chatgpt

19:10 <guso78> i got the communication wrong, your chat partner  othx '=D

19:13 <gbruno> [github] jbinvnt synchronize pull request #4330 (GSoC 2022: 3D Viewport Graphical Enhancements ) https://github.com/openscad/openscad/pull/4330

19:18 <joseph_> kintel: I'm online for the first day of the coding period. I saw that you mentioned me a couple days ago in #4595, and yes that's something we'll discuss. I'm also curious whether the user obliviand on GitHub is still around. While working last year I saw lots of contributions from Jason Childs in the blame, so he could be a good additional person to consult if possible

19:20 <gunnbr> :D

19:23 <kintel> joseph_ I haven't seen him around for a long time, but perhaps someone else has?

19:23 <gunnbr> seen obliviand?

19:23 <kintel> He did implement most or all of the VBO-related code, but IMO it needs significant refactoring as it tries to do too many variants and ended up being not very efficient

19:23 <othx> Sorry, I haven't seen obliviand.

19:23 <gunnbr> botsmack!

19:23 <othx> OUCH!!!

19:24 <gunnbr> botsnack!

19:24 <othx> YUM! This is why I love #openscad.

19:25 <kintel> In terms of the GLSL stuff. I did some investigations and concluded that the only reasonable solution is to update OpenCSG to use GLSL as well. I was mostly curious how you managed to get GLSL to work last time, and if it still works

19:31 <joseph_> Do you mean whether my changes for GSoC 2022 still work with the code on current master? That's something I could investigate today. A few minutes ago I restored my old gsoc-2022 branch but I kept your rebase on a different branch within my fork

19:34 <kintel> yeah, I'm interested in whether you can render using GLSL in preview mode without rendering artifacts

19:36 <kintel> A quick check could be to render in preview mode with Show Edges

19:36 <kintel> (on master - it should trigger rendering artifacts, but may work on certain GPUs)

19:37 <gbruno> [github] jbinvnt closed pull request #4330 (GSoC 2022: 3D Viewport Graphical Enhancements ) https://github.com/openscad/openscad/pull/4330

19:38 <joseph_> So is the problem being caused by one portion of the rendering pipeline using vertices from the fixed-function code, and another portion getting slightly different positions from the GLSL shader? Would this theoretically get fixed after everything is transitioned to modern OpenGL?

19:39 <kintel> I believe that's the problem

19:39 <kintel> Yes, if everything (including OpenCSG) uses GLSL to generate vertices, I believe that would solve the problem

19:42 <guso78> are you discussing about whats currently written as "#version 110" in the shaders ?

19:44 <kintel> guso78 even older; this is about fixed function vs. "!!ARBvp1.0" vs "#version NNN"
