Syntax

void ExpandToOneRingNeighbours
(
const TUniqueFunction< bool> & FilterF
)

Remarks

Add all triangles in vertex one-rings of current selection to set. On a large mesh this is quite expensive as we don't know the boundary, so we have to iterate over all triangles.

Return false from FilterF to prevent triangles from being included.
