Hello,

in my editor I need to add a new feature to create a bridge between two mesh points. I try to do it with a commercial software
and this is the result:

In the commercial software I specified two points on the two side of the mesh (P1, P2) and after a bridge is created.

I think the software use curvature information or do a sort of interpolation.
Have you some idea where to start, what are the parameters needed to do interpolation?

Thanks in advance.


Ale.

Not exactly sure what you mean by a "bridge", but you might want to look into splines / Bézier curves (easily adaptable to surfaces too, in case a "bridge" is a surface and not just a curve).

Most commercial software packages (Polyworks, Geomagics, etc.) use the term "Hole fill", and you'll probably have much better luck finding your answer on Google, using that term.

Here's a PDF that I found when I used the search term polygon hole fill algorithm in Google.

EDIT:
Maybe I assumed wrong. Are you talking about creating a polygon "bridge" (as I assumed), or are you just looking to create a curve-on-surface "bridge"?
