Abstract: In some implementations, a computing device can simulate a virtual parallax to create three dimensional effects. For example, the computing device can obtain an image captured at a particular location. The captured two-dimensional image can be applied as texture to a three-dimensional model of the capture location.

Thus, a virtual parallax can be introduced into the generated imagery for the capture location. When presented to the user on a display of the computing device, the generated imagery may have a three-dimensional look and feel even though generated from a single two-dimensional image.
