  • Display apparatus for the display of documents in a three-dimensional workspace
    Patent number: 6012072
    Abstract: An apparatus for displaying documents on a computer controlled display device provides a method for clipping. To clip a document is to restrict the viewable area of the screen object on the computer controlled display device associated with the document. A workspace viewer process maintains the documents in a three-dimensional virtual workspace. A document renderer and attribute-value pairs accomplish clipping in the virtual workspace. Clip stops constrain the clipping edges of a document so that the document may be clipped only to a specified set of positions.
