Abstract: Embodiments relate to navigating through a three dimensional environment on a mobile device using a single gesture. A first user input is received, indicating that two or more objects have touched a view of the mobile device. Two or more target locations on a surface of the three-dimensional environment corresponding to the two or more objects touching the view of the mobile device are determined. A second user input indicating that the two objects have performed a motion while touching the view of the mobile device is received. Camera parameters for the virtual camera, based on the received second user input, are determined. The virtual camera is moved within the three dimensional environment according to the determined camera parameters, such that the two or more target locations remain corresponding to the two or more objects touching the view of the mobile device. Moving the virtual camera may include zooming, rotating, tilting, and panning the virtual camera.

Abstract translation: 实施例涉及使用单个手势在移动设备上浏览三维环境。 接收到第一用户输入，指示两个或多个对象已经触及移动设备的视图。 确定与触摸移动设备的视图的两个或多个对象相对应的三维环境的表面上的两个或更多个目标位置。 接收指示两个对象在触摸移动设备的视图的同时执行动作的第二用户输入。 确定基于接收到的第二用户输入的虚拟摄像机的摄像机参数。 虚拟相机根据确定的相机参数在三维环境内移动，使得两个或多个目标位置保持对应于触摸移动设备的视图的两个或更多个对象。 移动虚拟相机可能包括缩放，旋转，倾斜和平移虚拟相机。
