|
|
*
|
|
* vtkEllipseArcSource is a source object that creates an elliptical arc
|
|
* defined by a normal, a center and the major radius vector.
|
|
* You can define an angle to draw only a section of the ellipse. The number of
|
|
* segments composing the polyline is controlled by setting the object
|
|
* resolution.
