    摘要: In a data processor controlled display system having three-dimensional objects laid out in a three-dimensional virtual workspace, the objects have associated there with respective collision barriers which are stored with their corresponding objects. Then during navigation via changing the users viewpoint in to the workspace, when this changing viewpoint encounters any collision barrier which is offset from its object by a selected distance D, the viewpoint stops. This distance of the barrier from the object is selected so as to stop the viewpoint at a distance sufficiently removed from its particular object so as to leave the user or viewer with a view of the workscape of sufficient scope to permit the viewer to select a different navigation path or path branch. In accordance with a further aspect of the present invention, the viewpoint is optionally provided with a similar collision barrier.

    摘要: A method and system for navigating through an opaque structure via a user on a display in a computer system. The method and system comprises the steps of determining if the opaque structure is within a predetermined distance of the user and changing the opaque structure to a translucent structure when the user is within the predetermined distance of the opaque structure. Accordingly through the use of the method and system, a user can navigate more easily and efficiently through a display, particularly in three-dimensional environments associated with such a display without becoming disoriented.

    摘要: A system, method and computer program are provided for a virtual three-dimensional workspace containing a plurality of three-dimensional objects which may be interactively addressed or accessed by the viewer or user to perform a variety of interactive functions. In addition to these objects, the present invention provides a two-dimensional workplane setup at the front of the three-dimensional workspace which the viewer selectively contains two-dimensional images corresponding to and resembling selected three-dimensional whereby the user may select either the three-dimensional object or its two-dimensional image to perform particular interactive functions.

    摘要: The problem addressed by this invention is that of resolving what occurs when a user's viewpoint comes into contact with an object residing in a three-dimensional workspace as the viewer navigates through that workspace. There are several possibilities in such a situation. For example, the viewer's viewpoint may be stopped and prevented from advancing further or it may penetrate the object. The instant invention provides a climbability property for objects in 3-D virtual environments. This property, when stored in the software along with the properties which define that object, can alter the viewer's viewpoint such that it will automatically be adjusted to simulate the behavior of climbing over the object.

    摘要: A method, system and program for including selections in the menu bar that are icons. The support for menus containing icons includes an algorithm in the memory of a processor that presents a menu bar with imbedded icons. The icons can be selected to present nested levels of menu driven functions that are associated with the particular icons. From the menu, a user can directly perform nested, hierarchial operations associated with the icon upon another icon or other objects on a display.

    摘要: A system, method and computer program are provided for a virtual three-dimensional workspace, wherein certain 3-D objects can automatically provide a view point on themselves, that also make other neighboring objects visible according to a hierarchy of relevance and proximity, in three- dimensional workspace. The system subsequently serves to orient the viewer upon completion of an interactive task with one of the functional objects in the three-dimensional workspace.
