Gets the boundary positions that surround the mesh. Three array elements (in the order x, y, z) constitute one position.

Read-only property

BoundaryPositions is not necessarily the same boundary positions used to compute the mesh. In many cases, new positions are introduced to compute a mesh that conforms to the ellipsoid surface. Therefore, BoundaryPositions may contain additional positions so that a Polyline Primitive defined with BoundaryPositions will be watertight next to a Triangle Mesh Primitive defined with Surface Triangulator Result.
