CurveLengthParameter Method (Double, Double, Double, Interval)
Gets the parameter along the curve which coincides with a given length along the curve.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll) Version: 5.1.50000.0 (5.0.20693.0)
Syntax
public bool LengthParameter(
	double segmentLength,
	out double t,
	double fractionalTolerance,
	Interval subdomain
)

Parameters

segmentLength
Type: SystemDouble
Length of segment to measure. Must be less than or equal to the length of the subdomain.
t
Type: SystemDouble
Parameter such that the length of the curve from the start of the subdomain to t is s.
fractionalTolerance
Type: SystemDouble
Desired fractional precision. fabs(("exact" length from start to t) - arc_length)/arc_length <= fractionalTolerance.
subdomain
Type: Rhino.GeometryInterval
The calculation is performed on the specified sub-domain of the curve rather than the whole curve.

Return Value

Type: Boolean
true on success, false on failure.
