Patent attributes
Systems and methods for supplying an open interface (e.g., web pages) for viewpoint navigation control of a three-dimensional (3-D) visualization of an object that is simple to create and fast and easy to use. This viewpoint navigation control application allows users to control the viewpoint in a 3-D environment by interacting with (e.g., clicking on) a 2-D hyperlink layout within a web browser (or other 2-D viewer with hyperlink capability). Position and orientation data for a selected viewpoint are transferred as part of a command message sent to the 3-D visualization application through an application programming interface when users select a hyperlink from a web page displayed by the 2-D layout application. The 3-D visualization application then retrieves data and displays a view of at least a portion of the 3-D model of the object with the predefined viewpoint specified in the command message.
