*
|
|
*
|
|
* vtkGeoSampleArcs refines lines in the input polygonal data
|
|
* so that the distance between adjacent points is no more than a threshold
|
|
* distance. Points are interpolated along the surface of the globe.
|
|
* This is useful in order to keep lines such as political boundaries from
|
|
* intersecting the globe and becoming invisible.
