Public Function PointAt ( 
	faceIndex As Integer,
	t0 As Double,
	t1 As Double,
	t2 As Double,
	t3 As Double
) As Point3d

faceIndex

Type: System.Int32
Index of triangle or quad to evaluate.

t0

Type: System.Double
First barycentric coordinate.

t1

Type: System.Double
Second barycentric coordinate.

t2

Type: System.Double
Third barycentric coordinate.

t3

Type: System.Double
Fourth barycentric coordinate. If the face is a triangle, this coordinate will be ignored.

Type: Point3d
A Point on the mesh or Point3d.Unset if the faceIndex is not valid or if the barycentric coordinates could not be evaluated.
