sphericalRegion edit page

The class sphericalRegion describes a region on the sphere that is bounded by small circles. For a list of normal vectors $$N_i$$ and coefficients $$\alpha_i$$ the region is defined as all vectors $$v$$ on the sphere that satify for all $$i$$ the condition

$v \cdot N_i \le \alpha_i$

## Input

 N vector3d alpha double (default is 0 which corresponds to a great circle)

## Class Properties

 N the normal vector3d of the bounding circles alpha the cosine of the bounding circle antipodal
