01:11 <InPhase> The number of git emails I've received about text scaling is at least 20 times more than the amount I'm concerned about text scaling. :)

14:26 <SamuelMarks> hi

14:28 <Scopeuk> Hi

14:30 <SamuelMarks> Do you think OpenSCAD would be easy to compile to the web? [WASM]

14:31 <Scopeuk> there is an existing webasm port

14:31 <Scopeuk> https://github.com/DSchroer/openscad-wasm

14:31 <Scopeuk> there are efforts to mainline it, teepee will remember more

14:32 <SamuelMarks> Sweet

14:34 <Scopeuk> there are a couple of working sites but I forget the addresses right now

14:34 <SamuelMarks> I'm building an [open-source] optical device. Can OpenSCAD be used to show how light can project through the model; à la Zemax?

14:35 <Scopeuk> openscad has no baked in optics/material proerties

14:36 <J1A84437262> !wasm

14:36 <J1A84437262> https://ochafik.com/openscad/

14:37 <Scopeuk> ahh yes the open flexure stuff

14:37 <SamuelMarks> J1A84437262: very cool

14:39 <J1A84437262> another was  openscad.cloud iirc

14:39 <Scopeuk> https://openscad.cloud/openscad/ specifically but yes

14:41 <SamuelMarks> Neat

14:42 <SamuelMarks> With my website I'm going to just ask the user a couple of questions in a webform and then render the STL, the code itself would expect too much from my users 😅

14:42 <Scopeuk> SamuelMarks another option for that is potentially to use the customiser and one of the existing web sites that support it

14:43 <Scopeuk> I know thingiverse do (although tis quite an old engine at this point) and I think one of the more recent contenders but I forget which

14:43 <SamuelMarks> Sweet

14:43 <Scopeuk> the customiser lets you take vertain variables and pout them on a control panel

14:44 <J1A84> make with tech http://openscad.org/about.html#related-projects

14:44 <SamuelMarks> Ahhh there are a lot of files https://gitlab.com/openflexure/openflexure-microscope/-/tree/master/openscad

14:47 <SamuelMarks> Shiny

14:49 <SamuelMarks> Oh shiiiii, that link was not minified

14:51 <SamuelMarks> Yeah I thought it was short

14:51 <SamuelMarks> :(

14:52 <SamuelMarks> Here's the link https://dpaste.org/RB2bu from https://www.thingiverse.com/thing:231265/files

14:52 <othx> SamuelMarks linked to "OpenSCAD smart phone to microscope/telescope adapter by Boogie" on thingiverse => 1 IRC mentions

15:05 <teepee> ouch

15:05 <SamuelMarks> yeah :( - the link killed my irssi buffer

15:06 <teepee> yes, WASM is integrated into the main build, master produces a WASM build too, the linked app may have some extra fixes though

15:12 <J1A84> had some url shortener  that deny WASM links .. too long i assume

15:12 <RoyK> perhaps we should have a bot here to autokick people spamming ;)

15:13 <teepee> seems overkill as long as that happens 3 times a year by accident

15:14 <J1A84> https://en.wikipedia.org/wiki/IRC_flood

15:16 <Scopeuk> as a general rule harsh enforcement is for wilful infringement not once in awhile accidents

15:16 <Scopeuk> I guess channel rate limit might work but it is so rarely a problem its not worth the potential limitation

15:17 <teepee> a kick would not be a harsh treatment, most clients try to reconnect anyway. it would probably shorten such accidents

15:18 <Scopeuk> true it said autokick, I read autoban

15:19 <Friithian> (pro tip /server purge in irssi will stop that)

15:21 <J1A84> like /quit Ü

15:24 <J1A84> or a SCCAM "safety control cable axe man"

18:38 <kiba> Hey. Is there a good tutorial for embossing svg images into openscad object

18:50 <InPhase> kiba: Not much to it really. linear_extrude(10) import("xubuntu_logo.svg");

18:50 <InPhase> kiba: If you want color discrimination as height, convert to png first and use surface()

19:00 <J1A84> use experimental roof

19:00 <J1A84> .oO no kiba left

19:01 <InPhase> Yep, and just in time to miss my answer.

19:02 <InPhase> I was going to elaborate on the tricks of surface, since I think it's a much nicer tool if you have a 3D surface goal and know how to use an image editor.

19:02 <Friithian> lmao webchatters

19:03 <InPhase> surface plus color manipulation and blurring can potentially get you some really nice 3D effects for really cheap.

19:06 <J1A84> i once tried a lithophane  with it .. but had to cut it with a different program cuz scad took hours

19:07 <InPhase> https://i.imgur.com/BRNwy8E.png

19:08 <InPhase> The top example was color treated and blurred with gimp, which took me basically no time at all.

19:09 <InPhase> I think we can agree that's a beautiful result. :)

19:13 <J1A84> .. i turned 3D objects into color shaded for height extraction and laser engravings

19:13 <InPhase> https://i.imgur.com/9X6dSRs.png For completeness, this was the result of my gimp manipulation. I basically inverted the text color and dropped it as a flattened image on a black background, then blurred.

19:13 <InPhase> Gaussian blur by 1.5

19:20 <J1A84> how long does that take to difference with a cube?

19:49 <InPhase> The emboss?

19:49 <InPhase> I can check.

19:49 <InPhase> as soon as I find the buried window...

19:52 <InPhase> 45 seconds with last release, 1.5 seconds with the master branch.

19:53 <InPhase> Neither is too bad. The boost in master is really nice though. :)

19:56 <InPhase> That's about 420 pixels wide, so scaled down 168mm in width at 0.4mm standard extruder step sizes.

19:57 <InPhase> So about max overhead for a smooth embossing label plaque on a standard printer.

19:59 <InPhase> Before I started doing it this way, I used to get terrible overheads trying to smooth surface() results with minkowski internally. The external blurs and adjustments make this much better performance-wise.

20:32 <J1A84> and that is not for rendering the surface but for a boolean operation with the surface?

22:52 <gbruno> [github] jordanbrown0 opened pull request #4306 (Add "em" parameter to text functions to set size of an em-square.) https://github.com/openscad/openscad/pull/4306

23:33 <InPhase> J1A84: Yeah, I did a difference with it for those times.
