VB

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

segmentLength

Type: System.Double
Length of segment to measure. Must be less than or equal to the length of the subdomain.

t

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

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 rather than the whole curve.

Type: Boolean
true on success, false on failure.
