Interaction of Objects in a Virtual Environment: A Two-Point Paradigm

摘要

Virtual environments are computer generated environments with computer generated objects. These objects will, in general, have interactions. Thus the construction and editing of virtual environments will involve the specification of interactions. This paper presents a way of viewing interactions, the two-point paradigm, which permits the user to view and edit interactions between pairs of objects in real time from within the environment. The two-point paradigm naturally suggests data structures for objects, interaction definition, and the actual interactions in the environment. These data structures are described, and a simple editor based on them is suggested.
