Operations

An object of this type must provide:

Comparison_result operator() (const SphericalKernel::Circular_arc_3 &a0, const SphericalKernel::Circular_arc_3 &a1, const SphericalKernel::Circular_arc_point_3 &p)
 Compares the \( z\)-coordinates of the intersection points of both arcs with a meridian anchored at the poles of the context sphere used by the function SphericalKernel::compare_z_to_right_3_object, at a \( \theta\)-coordinate infinitesimally greater that the \( \theta\)-coordinate of point p.

Comparison_result SphericalKernel::CompareZToRight_3::operator() ( const SphericalKernel::Circular_arc_3 &  a0,
const SphericalKernel::Circular_arc_3 &  a1,
const SphericalKernel::Circular_arc_point_3 &  p 
)

Compares the \( z\)-coordinates of the intersection points of both arcs with a meridian anchored at the poles of the context sphere used by the function SphericalKernel::compare_z_to_right_3_object, at a \( \theta\)-coordinate infinitesimally greater that the \( \theta\)-coordinate of point p.

Precondition
a0 and a1 lie on the context sphere used by the function SphericalKernel::compare_z_to_right_3_object, a0 and a1 are \( \theta\)-monotone, p lies on a0 and a1 and is not a \( \theta\)-extremal point of the supporting circle of a0 or a1.
