|
* @brief create a line defined by two end points
|
||
|
|
*
|
||
|
|
* vtkLineSource is a source object that creates a polyline defined by
|
||
|
|
* two endpoints. The number of segments composing the polyline is
|
||
|
|
* controlled by setting the object resolution.
|
||
|
|
*
|
||
|
|
* @par Thanks:
|
||
|
|
* This class was extended by Philippe Pebay, Kitware SAS 2011, to support
|
||
|
|
* broken lines as well as simple lines.
