OptionalfairRefine and fair each fill so it follows the surrounding curvature. Default true.
OptionalmaxFill only holes with at most this many edges; Infinity fills any size. Default 64.
OptionalminComponents with fewer triangles are removed; the largest always stays. Default 500.
OptionalweldVertices at most this far apart are welded, in mesh units. Default 1e-5.
The standard cleanup pipeline for Scene.repair: weld, remove degenerate, orient, remove small components, fill holes, as one transaction. The library owns the order; an option left out takes the library's default.
