00:38 <SD21> anybody know of a online render thats faster than 3dcustomizer.net

00:38 <SD21> stl*

00:49 <teepee> it already has Manifold enabled, so others should be pretty similar

00:50 <teepee> you can try https://ochafik.com/openscad2/

00:52 <SD21> thx

01:24 <Guest74> Hello everyone.

01:38 <teepee> hello Guest74 and good night :)

04:58 <J23k72> oh look at this https://github.com/jschobben/colorscad

05:13 <InPhase> Sounds like a hacky duct tape solution to achieving the goal with moderate reliability, but that fills an important void.

05:18 <J23k72> yes, but i wonder why can't we just use the CSG to order und union elements by color and export them into the 3mf with colors conserved

11:34 <tcurdt-> I have a hull of two circles (d1,d2) and want to distribute n things equally around the border of the hull.

11:34 <tcurdt-> That feels a lot harder than I first thought.

11:35 <tcurdt-> Nothing some math can't fix - but I am wondering if I am missing a simple approach.

12:09 <J23k72> tcurdt- you have  a belt  https://www.omnicalculator.com/physics/belt-length  so this end in two circle segments and two straight .. for equal distribution you need the length divided into n segments

12:10 <tcurdt-> Ah! I wasn't aware it's called a belt.

12:13 <tcurdt-> Now with that the length of the belt seems "easy enough" but dividing the border in n pieces still seems quite hard.

12:14 <tcurdt-> maybe I first need to find the tangential points.

12:17 <tcurdt-> https://en.wikipedia.org/wiki/Tangent_lines_to_circles seems to cover quite a bit

12:17 <InPhase> tcurdt-: There are some pretty bad hackery approaches trying to generate tiny points at vertices and then minkowskiing them with a target object, but it is broadly speaking a bad idea that I only found realworld appropriate once, and it doesn't even work for your hull problem. So, yeah, math that one.

12:19 <tcurdt-> yeah, it looks like nice evening of math problem ... a bit more complex than I though on the first glance

12:19 <tcurdt-> it always is I guess

12:36 <gbruno> [github] Dachtire closed issue #4740 (cylinder center parameter not work as expected) https://github.com/openscad/openscad/issues/4740

14:16 <J23k72> tcurdt- have this in my lib  ( not the distribution but that is not too difficult to add if you have all the numbers)

14:43 <InPhase> tcurdt-: The math probably gets easier with a good coordinate choice. Either both circle edges on the x-axis with one at the origin, or one circle at the origin and both on the x-axis, then rotate into place later.

14:45 <InPhase> tcurdt-: You can also apply an affine matrix to your calculated coordinates. after determining them this way, if you need the coordinates for final object placement in order to preserve a placed object orientation.
