ABSTRACT:
A method and apparatus for controlling shadow geometry on a computer display in an interactive computer display system. The method and apparatus comprises: maintaining primary element information defining a primary element; generating shadow geometry information defining a shadow geometry, the shadow geometry information having a predetermined mathematical relationship with the primary element, the shadow geometry information being generated in response to user manipulation of the primary element; integrating the shadow geometry with the primary element to form a single graphical unit (called a "par"); and selectively displaying the secondary element concurrently with the primary element.
