DigitalRuneICurveTParam, TPointGetLength Method
Computes the approximated length of the curve for the parameter interval [start, end].

Namespace: DigitalRune.Mathematics.Interpolation
Assembly: DigitalRune.Mathematics (in DigitalRune.Mathematics.dll) Version: 1.14.0.0 (1.14.0.14427)
Syntax
Copy
TParam GetLength(
	TParam start,
	TParam end,
	int maxNumberOfIterations,
	TParam tolerance
)

Parameters

start
Type: TParam
The parameter value of the start position.
end
Type: TParam
The parameter value of the end position.
maxNumberOfIterations
Type: SystemInt32
The maximum number of iterations which are taken to compute the length.
tolerance
Type: TParam
The tolerance value. This method will return an approximation of the precise length. The absolute error will be less than this tolerance.

Return Value

Type: TParam
The approximated length of the curve for the given parameter interval.
Remarks
For some curves the length is computed with an iterative algorithm. The iterations end when the maxNumberOfIterations were performed, or when the tolerance criterion is met - whichever comes first.
