Abstract: The capability to render and navigate three-dimensional panoramic images in a virtual three-dimensional environment so as to create an immersive three-dimensional experience is provided. Such a capability can present a three-dimensional photographic experience of the real world that is seamlessly integrated with the virtual three-dimensional environment. Depth values associated with the panoramic images may be used to create three-dimensional geometry, which can be rendered as part of the virtual three-dimensional environment. Further, such a capability can enable a user to roam freely through the environment while providing a more natural free-form exploration of the environment than existing systems.

Abstract translation: 提供了在虚拟三维环境中渲染和导航三维全景图像以产生沉浸式三维体验的能力。 这样的能力可以呈现与虚拟三维环境无缝集成的现实世界的三维摄影体验。 与全景图像相关联的深度值可以用于创建三维几何，其可以作为虚拟三维环境的一部分呈现。 此外，这样的能力可以使用户能够自由地漫游环境，同时提供比现有系统更自然的自然形式的环境探索。

Abstract: 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.

Abstract translation: 提供了用于在三维环境中导航虚拟相机的分级相机遍历。 分阶段的相机穿越可以包括发射阶段和进场阶段。 在发射阶段期间，倾斜角度可以相对于垂直方向朝向零倾斜（即，向下）减小。 在接近阶段期间，可以将虚拟照相机的倾斜角度从大约零倾斜增加到与目标位置相关联的倾斜角度。 在某些实施方案中，分级摄像机遍历还可以包括在发射台和接近台之间发生的遍历阶段。 虚拟相机的倾斜角度可以在遍历阶段保持在大约零倾斜度。 在接近阶段期间，可以沿着与目标目的地相关联的视图方向对准虚拟摄像机的进场路径。
