/**

* @class vtkAppendArcLength
|
||
|
|
* @brief appends Arc length for input poly lines.
|
||
|
|
*
|
||
|
|
* vtkAppendArcLength is used for filter such as plot-over-line. In such cases,
|
||
|
|
* we need to add an attribute array that is the arc_length over the length of
|
||
|
|
* the probed line. That's when vtkAppendArcLength can be used. It adds a new
|
||
|
|
* point-data array named "arc_length" with the computed arc length for each of
|
||
|
|
* the polylines in the input. For all other cell types, the arc length is set
|
||
|
|
* to 0.
|
||
|
|
* @warning
|
||
|
|
* This filter assumes that cells don't share points.
