WebApr 13, 2024 · The definition of sphere is a 3D closed surface where every point on the sphere is same distance (radius) from a given point. The equation of a sphere at the origin is . Since we cannot draw all the points on a sphere, we only sample a limited amount of points by dividing the sphere by sectors (longitude) and stacks (latitude). WebJul 9, 2024 · To find the surface distance between two points and on the unit sphere, note that the shortest path on the sphere between and is a great circle arc. By the previous observation, we find that the spherical distance is Generalizing this to spheres of radius , …
