damnit I was planing on printing something on that bit of my bed

hm... if I have this matrix, sylinderbredder = [27,27,32];, and I want to iterate through it, is it possible to get an index (0- or 1-based, doesn't matter) with it without adding another column for that?

RoyK you add a loop (i=[0:1]) or make a condition let ( i=sylinderbredder==27?1:0)

teepee, with my size is see deformation on polygons already, not on only on volumes which could easily be solved by an ray -algorithm counting the area/line overlap and doing union as >= 1 algorithm. I like to test this Manifold now. will look on github next
<guso78>
i have found many manifold projects, but none which is CSG related ..

time to recreate something I made badly in freecad in openscad

thankfully it is fairly straight forward

<guso78>
in my latest PR the new python primitive test has failed with Error 8, whereas it was ok in my place.
<guso78>
can somebody tell me, what went wrong ?
<guso78>
segfault ? did not run, could not compare, ???

teepee, are you there ?
<teepee>
present yes
<teepee>
but busy and sleepy
<teepee>
bad combination :)
<guso78>
sorry to disturb ...
<guso78>
its much work rather than fosdem, right ?
<teepee>
yes, fosdem did not work out this year
<InPhase>
guso78: Looks like you fixed the segfault in that testcase I had posted. So that's progress!
<InPhase>
guso78: Now it just has to actually do some sort of offset. :)
<InPhase>
I thought I'd check in on the status of it.

<guso78>
InPhase, i am not yet happy with offset after you showed given me some testcase
<guso78>
offset just works in ideal case. as soon as points swap position in a bad manner, there is polygon degeneration and all successive mess
<InPhase>
Yeah. My testcase is based on a bunch of thoughts I had years back when thinking about the worst cases that would make a 3D offset hard to do.
<guso78>
i believe, that a line tracing algorithm ( aka plane tracing algorithm could fit all of that)
<InPhase>
I'm confident it's still doable. Just, there are the tricky parts.
<guso78>
once i have offset finished, i have an exact idea how to do rounded offsets
<guso78>
then: you can do offset(-3) and then offset(3, round=True) to create round edges on ANY existing object
<guso78>
Today i was able to create a small executable using Manifold library, and i was able to create a Manifold::Cube object, but i could not find a way to output it ....
<guso78>
InPhase, how can i find out,why my PR to python-support was not successful ? my added ctest failed, but i dont know why
