any time you need to generate a sphere with x-number of faces, it's a stupid interview question yeah but any programmer should be able to figure out or at least describe such an algorithm at a high level, you could use the generated vertex coordinates to do tons of stuff like collision detection or various object interactions according to the normal vectors of the faces or edges, or use the sphere as a distance limit to poll for nearby objects or whatever, there are unlimited uses, hell you could just use a cube instead if you wanted it to be simpler
