With a single click, you can view the 3-D image of a sedan or a sports car on a Web site of global automakers like Honda and Nissan. With another click, you can change the color and model, or even rotate the vehicle.

This is no longer only possible on PCs. Turn on a state-of-the-art mobile phone, key in the right sequence and you can also make 3-D objects pop up on the screen.

This technology has made Yappa Corp., an information technology startup, grow stunningly fast.
