Public Function IsManifold ( 
	topologicalTest As Boolean,
	<OutAttribute> ByRef isOriented As Boolean,
	<OutAttribute> ByRef hasBoundary As Boolean
) As Boolean

topologicalTest

Type: System.Boolean
If true, the query treats coincident vertices as the same.

isOriented

Type: System.Boolean
isOriented will be set to true if the mesh is a manifold and adjacent faces have compatible face normals.

hasBoundary

Type: System.Boolean
hasBoundary will be set to true if the mesh is a manifold and there is at least one "edge" with no more than one adjacent face.

Type: Boolean
true if every mesh "edge" has at most two adjacent faces.
