    摘要： One embodiment of the present invention sets forth a technique for providing an end user with a multiscale three-dimensional (3D) navigation experience in design software application programs. An adaptive multiscale 3D navigation system allows an end user to transition between a planetary scale down to an individual building scale. The end user may navigate within the building, inspecting object details within the building. The size of the environment is sensed automatically, and the viewing and travel parameters are adjusted accordingly to provide the end user with a seamless navigation experience. A consistent navigation experience is supported at various scales, and real-time collision detection is provided. Scale computation for 3D scenes and collision detection may be based on a generated depth cubemap of the environment.

    摘要： A method, apparatus, and article of manufacture provide the ability to control a three-dimensional scene view. A three-dimensional (3D) scene having one or more three-dimensional objects is displayed. A 3D representation of a coordinate system of the scene is displayed. The 3D representation contains a current viewpoint, one or more faces, one or more edges, and one or more corners with each face, edge, and corner representing a corresponding viewpoint of the scene. The 3D representation is manipulated. A new current viewpoint of the 3D representation is displayed based on the manipulation. The scene is then reoriented corresponding to the new current viewpoint based on the manipulation of the 3D representation.
