comment Which 3D algorithms does Windows 10's “3D Builder” application use?
@doug65536, it looks like the question was reopened, if you want to post an answer.

Changing the actual question to match a recommendation from @MetaFight

That's fair to say. Thank you for the advice, I've restructured the question as you recommended. I'm leaving the MS-specific followups in place, but I agree that the question is answerable without considering the implementation detail.

comment Which 3D algorithms does Windows 10's “3D Builder” application use?
Because 20 years of programming on the Microsoft stack has taught me little is more futile than asking Microsoft, even through MSDN, about the implementations of their own programs; they're simply not structured so that their code becomes documented. I thought a graphics programmer looking here would see the wireframes change and be able to suggest something robust. Instead I see that an hour can't go by without someone starting a closure wave. This is a narrow question with two followups: Which algorithms do these things to triangle meshes?

Microsoft people don't look here? I thought we were crowdsourced.

comment Scrum for a single programmer?
Such irony. Closed as "too broad" after 3 1/2 years, where the last activity was only slightly less old than that. And it's still getting upvoted!

comment Selecting a point inside a non-convex polygon
That's an approach, but, my polygons are not on a screen; they're computed from a cut-point of a 3-d triangle mesh, out of which the segments are taken and ordered.

comment Selecting a point inside a non-convex polygon
Not quite; my PSLGs are far more complex than triangles, though I could see how an incentre computation could form a part of the full algorithm.

comment Selecting a point inside a non-convex polygon
@PeterTaylor, I feel like I have to be sensitive to computational complexity; some of my PSLGs will have thousands of line segments. Otherwise I'd just proceed with my initial thinking.

comment Selecting a point inside a non-convex polygon
@mjfgates, the Non-Convex polys in this case will always have an inside. I can write the algorithm to catch that edge case and fail gracefully, doing nothing.

comment Selecting a point inside a non-convex polygon
@JayElston, the point on an edge is considered "outside"; otherwise the algorithm would be very easy: return the first point on the first edge. But thank you; it's not a case I'd considered and upon reflection also not a case I need to consider.

That doesn't at all sound like it would be efficient...

comment Selecting a point inside a non-convex polygon
I would prefer to favor points which are not close to edges.

comment Generate complex (non-convex) polyhedron UV mapping
The simulation results are uniform (non-sparse) 3D arrays containing single precision values. There is a neighboring array of short integers which approximates the 3D mesh; a "1" value in that array corresponds to a part of the enclosed region of the polyhedron. I'm mapping to non-convex 3D surfaces more complex than can be mapped with a simple unrolling texture mapper or a spherical ray casting approach. Think of an American gallon milk jug or similar shapes that can be produced in plastic or metal molds.
