C#

public int[] GetConnectedFaces(
	int faceIndex,
	double angleRadians,
	bool greaterThanAngle
)

VB

Public Function GetConnectedFaces ( 
	faceIndex As Integer,
	angleRadians As Double,
	greaterThanAngle As Boolean
) As Integer()

faceIndex

Type: System.Int32
face index to start from

angleRadians

Type: System.Double
angle to use for comparison of what is connected

greaterThanAngle

Type: System.Boolean
If true angles greater than or equal to are considered connected. If false, angles less than or equal to are considerd connected.

Type: Int32[]
list of connected face indices
