09:24 <mmj> hi, i exported a model to obj. but the file is different from the obj i get from blender.

09:28 <Guest26> We posted our Stepwell Project here: https://www.thingiverse.com/thing:7082741 Thank you a lot for your support! <3

09:28 <othx> Guest26 linked to "Customizable stepwell inspired by Chand Baori by dieBetreppten" on thingiverse => 1 IRC mentions

09:40 <J25k39> mmj probably color information?  geometry should be the same

09:41 <mmj> i am talking about faces

09:42 <J25k39> Guest26 nice! that is a cool demo for parametrical design https://www.youtube.com/watch?v=lCWTokPiP28

09:42 <othx> J25k39 linked to YouTube video "Promotional video for a highly customizable 3D model of a stepwell: the Stepwell Project" => 2 IRC mentions

09:44 <J25k39> mmj if you render something there might be different algorithms but it should not change the geometry but sometimes there are multiple faces valid

09:44 <J25k39> you get different results if using manifold or cgal

09:45 <J25k39> but within the floatingpoint precision they should all show the same geometry

09:46 <mmj> i meant this:

09:46 <mmj>

09:46 <mmj> blender

09:46 <mmj> f 5/1/1 3/2/1 1/3/1

09:46 <mmj>

09:46 <mmj> openscad

09:46 <mmj> f 5 1 1

09:46 <mmj> f 3 2 1

09:46 <mmj> f 1 3 1

09:54 <J25k39> probably both are valid - don't have read the spec

09:55 <mmj> can you give an option in the exporter to choose between the two.

09:57 <J25k39> https://en.wikipedia.org/wiki/Wavefront_.obj_file  show that both seem to be ok

09:58 <J25k39> mmj you can always open a feature request

09:59 <mmj> in github isssues?

10:00 <J25k39> yes you can select what kind of issue you like to open

10:01 <mmj> ok, thanks i will do that

10:02 <bitbasher> does anyone know where i can look up the argument list for modules like import() and so on .. and i would also like to look at the function and argument name completion stuff in the built in editor

10:03 <J25k39> cheatsheet!

10:03 <othx> cheatsheet is https://www.openscad.org/cheatsheet/ for the release version and https://www.openscad.org/cheatsheet/snapshot.html for the development snapshot versions

12:16 <teepee> bitbasher: the only 100% safe answer is "in the code" which is why I'd like to generate that info automatically at some point

13:35 <Guest30> Suppose that one starts with right handed coordinate system (x, y, z) ~ (index, middle, thumb) of right hand. Is there a way to somehow manipulate camera in openscad, without any code edit, but only moving mouse while left button clicked, to flip it to a left handed system:  (y, x, z) ~ (index, middle, thumb) (of right hand)?

16:12 <InPhase> Pretty sure I labeled that a bug the last time I saw the coordinates inverting in OpenSCAD from mouse manipulation. :)

16:13 <InPhase> Turning the universe inside out is an awkward manipulation.

16:13 <teepee> true, but it sounds like that is what they were asking

16:13 <teepee> I suppose the answer would have been "not possible" then

16:13 <InPhase> Flipping chirality gets you things like bizzaro superman. One must be careful.

16:18 <teepee> yeah, too much bizzaro people around already :/

16:19 <InPhase> But I am left wondering what the aspiration was that led to a user intentionally looking for this as a feature.

16:19 <teepee> maybe matching coordinates to some other tool? who knows

18:24 <gbruno> [github] kintel opened issue #6013 (Manifold union result not convertible to Nef polyhedron via Surface_mesh) https://github.com/openscad/openscad/issues/6013

21:33 <bitbasher> Othix and J25 .. i know about the cheat sheets .. i am trying to verify the operation of the functions and methods to update them .. thus the need to find the code and the scintilla editor features to know what correct looks like

21:35 <bitbasher> for instance, i have already seen that the completion information for linear_extrude is missing the direction vector parameter 'v' and a set of parameters are supposed to be given in a vector .. except that is not really the case

23:17 <bitbasher> an IP only user dropped a script for generating a sports car into the top level page of the Wiki Language Ref - General page .. i have moved the code to my sandbox .. u can find the link to that in the discussion page on General .. or just look for VulcanWikiEdit and see my sandbox from there

23:17 <bitbasher> night all zzzzzz
