This invention relates to navigating in a three dimensional environment. In an embodiment, a target in the three dimensional environment is selected when a virtual camera is at a first location. A distance between the virtual camera and the target is determined. The distance is reduced, and a tilt is determined as a function of the reduced distance. A second location of the virtual camera is determined according to the tilt, the reduced distance, and the position of the target. Finally, the camera is oriented to face the target, hi an example, the process repeats until the virtual camera is oriented parallel to the ground, and the distance is close to the target. In another example, the position of the target moves.
