graphics noob question, OpenGL, Metal or SceneKit

Hi guys, long time iphone programmer but noob to 3D graphics, i'm just looking for some advice as to how to approach the following problem.

I need to have a sphere (not a cube) on which to project a picture. Camera will be at the center of the sphere and should rotate with the phone rotation. At all times i need to grab the XY position of the original image that aligns with the camera's direction.

So, being a noob to 3D, which would be the best / less painful way to achieve this? OpenGL ES, Metal? or SceneKit?

Any pointers are appreciated
