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 satisfy for all \(i\) the condition
\[v \cdot N_i \le \alpha_i\]
Syntax
sR = sphericalRegion(N)
sR = sphericalRegion(N,alpha)
sR = sphericalRegion(N,'antipodal')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 |
