Detailed Description

create a circular arc

vtkArcSource is a source object that creates an arc defined by two endpoints and a center. The number of segments composing the polyline is controlled by setting the object resolution. Alternatively, one can use a better API (that does not allow for inconsistent nor ambiguous inputs), using a starting point (polar vector, measured from the arc's center), a normal to the plane of the arc, and an angle defining the arc length. Since the default API remains the original one, in order to use the improved API, one must switch the UseNormalAndAngle flag to TRUE.

The development of an improved, consistent API (based on point, normal, and angle) was supported by CEA/DIF - Commissariat a l'Energie Atomique, Centre DAM Ile-De-France, BP12, F-91297 Arpajon, France, and implemented by Philippe Pebay, Kitware SAS 2012.
