Sphere angle
WebWhen the directions correspond to points on a sphere, this is the angle between two line-segments (or rays) connecting the center of the sphere and each of those points, in the plane which contains all three points (and both line-segments/rays). The magnitude of this angle can found using the spherical law of cosines: Websphere, In geometry, the set of all points in three-dimensional space lying the same distance (the radius) from a given point (the centre), or the result of rotating a circle about one of …
