Object Selection in 3D Environments
A method for object selection of 3D objects in a computer-generated 3D environment
The U.S. Navy seeks to commercialize U.S. Patent 7,348,997 (Object selection in a computer-generated 3D environment).
Current object selection techniques in 3D computer-generated environments require the end-user to place a cursor directly on an object in order to select it and only provide feedback after the user selects an object. Tightly clustered, overlapping, or hidden objects are difficult if not impossible to select or gather information on.
SSC Pacific has developed both a method and system that allows for the selection and pre-selection of objects in a 3D computer-generated environment. Users have the ability to view 3D objects situated on the screen, as well as change the view of the screen to select objects otherwise hidden. The technology assists the user in selecting many items, such as pre-selecting the closest object, and identifying the next closest object subsequent to the first. Additionally, the technology facilitates the selection of multiple objects based on user-defined settings. This all combines to create a computationally quick and efficient object selection technique without worrying about the exact placement of the cursor. Additionally, it allows for the previously unavailable simple selection of relatively small or tightly clustered objects in a 3D computer generated scene.
