bool SphericalKernel::Equal_3::operator() ( const SphericalKernel::Circular_arc_3 a0,
const SphericalKernel::Circular_arc_3 a1 
)

For two arcs.

Two arcs are equal, iff their non-oriented supporting planes are equal, and the centers and squared radii of their respective supporting circles are equal, and their sources and targets are equal.

bool SphericalKernel::Equal_3::operator() ( const SphericalKernel::Line_arc_3 a0,
const SphericalKernel::Line_arc_3 a1 
)

For two segments.

Two segments are equal, iff their non-oriented supporting lines are equal (i.e. they define the same set of points), and their endpoints are the same.
