CurveNormalizedLengthParameters Method (Double, Double, Double, Interval)

Input the parameter of the point on the curve that is a prescribed arc length from the start of the curve.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 5.0
public double[] NormalizedLengthParameters(
	double[] s,
	double absoluteTolerance,
	double fractionalTolerance,
	Interval subdomain


Type: SystemDouble
Array of normalized arc length parameters. E.g., 0 = start of curve, 1/2 = midpoint of curve, 1 = end of curve.
Type: SystemDouble
If absoluteTolerance > 0, then the difference between (s[i+1]-s[i])*curve_length and the length of the curve segment from t[i] to t[i+1] will be <= absoluteTolerance.
Type: SystemDouble
Desired fractional precision for each segment. fabs("true" length - actual length)/(actual length) <= fractionalTolerance.
Type: Rhino.GeometryInterval
The calculation is performed on the specified sub-domain of the curve. A 0.0 s value corresponds to sub-domain->Min() and a 1.0 s value corresponds to sub-domain->Max().

Return Value

Type: Double
If successful, array of curve parameters such that the length of the curve from its start to t[i] is s[i]*curve_length. Null on failure.
