Method Detail
adjacent()method
public function adjacent(nGon:NGon):Boolean

Tests if two NGons (partially) share an edge.

Parameters

nGon:NGon — The NGon to test against.

Returns
Boolean — Whether or the target NGon shares an edge with the current NGon.
classifyToPlane()method 
public function classifyToPlane(compPlane:Plane3D):int

Parameters

compPlane:Plane3D

Returns
int
clone()method 
public function clone():NGon

Creates a duplicate of this NGon

Returns
NGon
fromTriangle()method 
public function fromTriangle(face:Face):void
