How detect unshared edges pair for PolyBridge?

Recommended Posts

Posted (edited)

Hi. I want to convert these surface geometries to solid geometry.
PolyFill SOP cannot make surface with hole for this type topology, so now we have to use Polybridge SOP.
They have two unshared edges facing each other, selecting edges manually, we can get natural solid geometry by PolyBridge SOP.
But now I have to do this process procedural.
Anyone have simple ideas?

Input : like clipped torus

Input : Rubber parts of Tire model often lost their inside surface

assuming you always have 2 independent unshared groups with opposite winding you can do this

well that's a use of divide I've never seen before!!!

Thanks everyone!
Noobini's ExtrudeVolume SOP and Hole SOP combination for unshared edge is nice, I can use anywhere.
anim's method is incredible, this network can fix  even four columns tube topology!

just note in my ray...there's a tiny teeny bit of jitter scale...without it...some points wont' find their targets.
