void ExpandToOneRingNeighbours
(
const TUniqueFunction < bool> & FilterF
)
Remarks
Add all triangles in vertex one-rings of current selection to set. On a large selection this is quite expensive as we don't know the boundary, so we have to iterate over all selected triangles.
Return false from FilterF to prevent triangles from being included.
