VB

Public Function NormalizedLengthParameter ( 
	s As Double,
	<OutAttribute> ByRef t As Double,
	fractionalTolerance As Double,
	subdomain As Interval
) As Boolean

s

Type: System.Double
Normalized arc length parameter. E.g., 0 = start of curve, 1/2 = midpoint of curve, 1 = end of curve.

t

Type: System.Double
Parameter such that the length of the curve from its start to t is arc_length.

fractionalTolerance

Type: System.Double
Desired fractional precision. fabs(("exact" length from start to t) - arc_length)/arc_length <= fractionalTolerance.

subdomain

Type: Rhino.Geometry.Interval
The calculation is performed on the specified sub-domain of the curve.

Type: Boolean
true on success, false on failure.
