How would I go about creating a 3D globe in unity that I can zoom in and out of and rotate in each direction around?
This would be similar to the globes in the game “Spore”.
I think for zooming in you could use Camera.fieldofview . And for rotating it sounds like you’d have more luck with a rigidbody (look at its members to see which one would suit your needs)
in opposite to paparakas i suggest you should just move the camera. changing fov creates perspectivic distortions.
regarding the globe have a look at this (another example why forum search is helpfull): http://forum.unity3d.com/threads/198260-Spherical-Terrain-Shader
