<kintel> Warning: I'm going to merge this rather large refactoring, so if anyone finds rendering errors, you know who to blame :) https://github.com/openscad/openscad/pull/4933

<guso78k> does anybody know a good algorithm to find out, if one polygon is INSIDE another polygon in 3D Space ? the polygons share the same plane and they dont intersect.
<guso78k> background: i want to attach the holes back to its outside boundary

<greyltc> Hi, hull() doesn't work as I expect.
<greyltc> I hoped I should be able to make a 3d shape by calling hull on two 2d child objects
<greyltc> like this:
<greyltc> hull(){translate([-5,0,-10]) circle(d=10); translate([+5,0,10]) circle(d=10);}
<greyltc> But it seems the child objects are projected onto the z=0 plane and then hull is run on that, giving a 2d result
<greyltc> Is there any library or anything that gives me a function like hull() that can make 3d objects given 2d children?
