Parameters
- start
- Type: SystemSingle
The parameter value of the start position. - end
- Type: SystemSingle
The parameter value of the end position. - maxNumberOfIterations
- Type: SystemInt32
The maximum number of iterations which are taken to compute the length.
- tolerance
- Type: SystemSingle
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:
Single
The approximated length of the curve for the given parameter interval.
Implements
ICurveTParam, TPointGetLength(TParam, TParam, Int32, TParam)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.
