摘要： A multiscale data engine is configured to generate a three-dimensional (3D) environment based on a multiscale 3D dataset. The multiscale data engine is also configured to generate a spatial hierarchy within the 3D environment by selectively grouping 3D objects within the 3D environment. The multiscale data engine is further configured to identify specific 3D objects within the 3D environment in response to input received from an end-user and based on spatial properties associated with the 3D objects. The multiscale data engine is also configured to generate various navigation graphical user interfaces (GUIs) that allow the end-user to navigate the 3D environment.

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.
