Any asset or code example for controller similar to google-street-view for mobile?

Hi there,

I want to implement to implement a controller (user interface) similar to google-street-view for mobile. More specifically, that user interface has following features.

• Zoom in/out by Pinching.

• Rotate the camera by swiping.

• Move the camera with smooth animation by touching the road.

• Focus on the object by touching the object.

• Show some "indicator" so user knows which is the road to move or which is object to focus.

Is there any existing asset or code example? I think it is kind of common requirement.

Thanks in advance.
