发明名称 Staged Camera Traversal for Three Dimensional Environment
摘要 A staged camera traversal for navigating a virtual camera in a three dimensional environment is provided. The staged camera traversal can include a launch stage and an approach stage. During the launch stage, the tilt angle can be decreased towards zero tilt (i.e. straight down) with respect to the vertical. During an approach stage, the tilt angle of the virtual camera can be increased from about zero tilt towards the tilt angle associated with a target location. In certain implementations, the staged camera traversal can further include a traversal stage occurring between the launch stage and the approach stage. The tilt angle of the virtual camera can be maintained at about zero tilt during the traversal stage. The approach path of the virtual camera can be aligned along a view direction associated with the target destination during the approach stage.

主权项 1. A computer-implemented method of navigating a virtual camera, comprising: presenting a view of a three dimensional model from a virtual camera at a first location, the virtual camera having a first tilt angle at the first location; receiving a user input requesting transition of the virtual camera to a second location, the virtual camera having a second tilt angle at the second location; and responsive to the user input, transitioning the virtual camera from the first location to the second location according to a staged camera traversal having a launch stage and an approach stage; wherein transitioning the virtual camera from the first location to the second location according to the staged camera traversal comprises decreasing a tilt angle of the virtual camera from the first tilt angle towards zero tilt during the launch stage and increasing the tilt angle of the virtual camera towards the second tilt angle during the approach stage.
