02:36 <kintel> teepee Haven't progressed much with removing any CGAL stuff. I'm too many levels deep in refactoring

02:37 <teepee> kintel: no problem, we can either look at making the measurement stuff work with CGAL too, or just ignore the issue for a while and see how it goes :)

02:39 <kintel> Not sure it's going to be worth adding in the short term, at least as long as manifold support is blocking the next release

02:42 <teepee> yeah, I tend to think it might be better to see if we can improve/extend the features instead of wading through those NEF datastructures

15:23 <kintel> pca006132 Still slowly progressing with VBO benchmarks. One thing I'm seeing so far: If you enable the first 3 VBO option (i.e. all of them _except_ -indexed), the performance is close to no VBO for a single frame, and much much better for subsequent frames.

15:23 <kintel> ..so rule is (for now), always enable the 3 first VBO options together. I plan to merge them into one soon.

15:24 <kintel> If you find any evidence otherwise, let me know :)

16:01 <linext_> anyone think of a better name than "reseller ruler" for this? https://resellerruler.com/wp-content/uploads/2023/03/Untitled-design-22-e1679467363279.png

16:02 <buZz> linext_: shirtsizer?

16:02 <buZz> garment ...something with a g

16:02 <linext_> pretty good, at first i thought you wrote shitsizer

16:03 <buZz> maybe just '2D ruler'

16:03 <linext_> yea, it's actually a double ruler

16:04 <linext_> https://ibb.co/album/PwYJbs

16:04 <buZz> XY ruler?

16:05 <linext_> merchant meter

16:05 <linext_> sales scale

16:07 mmu_man has quit [Ping timeout: 252 seconds]

16:08 <linext_> maybe instead of shirt sizer, stuff sizer

16:09 <linext_> since it can be used for a lot of stuff

16:11 <buZz> i wouldnt know what i'd use that for :D

16:11 <buZz> DImENSIONIZER

16:11 <buZz> lol

17:04 <pca006132> btw is there anything stopping the tracy integration?

17:07 <pca006132> kintel: is the -indexed option slowing things down?

20:07 <kintel> pca006132 Oh, sorry you were out sick, nothing urgent, just dropping my thoughts here from time to time :)

20:07 <kintel> Yeah, -indexed is really slow; I think it reindexes the indexed polysets in a very slow way

20:08 <kintel> I will clean that up after I deal with the non-indexed stuff

20:08 <kintel> Some stats: https://github.com/kintel/openscad-benchmark

20:33 <guso78k> kintel, ideally we skip reindexing indexed pts . do you focus on a special location in code ?

20:35 <teepee> where is that "b", "ba", ... coming from?

20:36 <teepee> from the assignment?

20:38 <teepee> all the string usage seems a bit awkward

20:40 kintel has joined #openscad

20:41 <kintel> guso78 yeah, the indexing code needs to be rewritten, but I need to clean up a lot of mess first

20:42 <teepee> just wondering... are you talking about the same indexing? like vbo vs. polyset?

20:45 <kintel> This is about the VBO renderer creating its own indexed polygons, even though the polyset is already indexed

20:45 <kintel> ..but it's not as simple as just using the existing index, as I believe the VBO renderer can merge multiple polysets into the same VBO

20:46 <kintel> Some of the code lives here: https://github.com/openscad/openscad/blob/master/src/glview/VertexArray.cc#L90

20:47 <kintel> Anyway, my tentative plan is: 1. reduce the VBO options to two options (non-indexed and indexed), 2. Make non-indexed the default and kill non-VBO code paths 3. Look into the indexed stuff

20:47 <kintel> ..without introducing bugs and performance regressions :)

20:50 <guso78> Polyset is only Indexed recently . Before indexing in vbo was OK 😜
