Fairs a curve object. Fair works best on degree 3 (cubic) curves. Attempts to remove large curvature variations while limiting the geometry changes to be no more than the specified tolerance.

)

VB

Public Function Fair ( 
	distanceTolerance As Double,
	angleTolerance As Double,
	clampStart As Integer,
	clampEnd As Integer,
	iterations As Integer
) As Curve

distanceTolerance

Type: System.Double
Maximum allowed distance the faired curve is allowed to deviate from the input.

angleTolerance

Type: System.Double
(in radians) kinks with angles <= angleTolerance are smoothed out 0.05 is a good default.

clampStart

Type: System.Int32
The number of (control vertices-1) to preserve at start. 0 = preserve start point

1 = preserve start point and 1st derivative

2 = preserve start point, 1st and 2nd derivative

clampEnd

Type: System.Int32
Same as clampStart.

iterations

Type: System.Int32
The number of iteratoins to use in adjusting the curve.

Type: Curve
Returns new faired Curve on success, null on failure.

Supported in: 6.0.16224.21491, 5D58w
