Very simple project. I need you to create a sphere in unity. Place a camera in the centre of the sphere.
Assign a texture to the sphere. Flip its normal if needed for texture to be visible to the camera.
The app needs to be exported as a android game so that we can see the whole sphere by moving the mobile with respect to accerlerometer of the mobile.
In explanation..when i move the mobile the part of the sphere in that texture should appear. Hope you understood my requirement clearly.
