ABSTRACT
See-through head-mounted display capability is becoming an important part of Virtual
Environment applications. In such applications, it may be desirable to model the physical
behavior of the virtual objects and their interaction with the real objects. This paper describes a
software system which integrates interactive collision detection, collision response and see-
through head-mounted displays. The system employs a static model of the real world
environment and allows for arbitrary convex virtual objects to be placed in the environment. The
user may control the positions and velocities of the virtual objects. An approximately constant
time collision detection algorithm and a Newtonian Mechanics based single point contact
collision response is used to model the apparent physical interaction of the virtual and real
objects for moderately complex environments.
