In an application, i saw that they used to display pictures of vehicles. But what was amazing was when we touch and swipe in that picture, it rotates in 3d way left and right. And from the front view we can rotate and get to see its back view also. It is a very good feature and i was trying to replicate it. But couldnt get an idea of how and where to start. My doubts are
Whats the actual format of the thing, it surely isn't a picture.
How do they get to rotate it?
Could someone give me an idea where i should start or where I should look upon?
