Conformal Tracking For Virtual Environments, Larry Dennis Davis Jr.
Conformal Tracking For Virtual Environments, Larry Dennis Davis Jr.
Electronic Theses and Dissertations
A virtual environment is a set of surroundings that appears to exist to a user through sensory stimuli provided by a computer. By virtual environment, we mean to include environments supporting the full range from VR to pure reality. A necessity for virtual environments is knowledge of the location of objects in the environment. This is referred to as the tracking problem, which points to the need for accurate and precise tracking in virtual environments. Marker-based tracking is a technique which employs fiduciary marks to determine the pose of a tracked object. A collection of markers arranged in a rigid …
Dynamic Shared State Maintenance In Distributed Virtual Environments, Felix George Hamza-Lup
Dynamic Shared State Maintenance In Distributed Virtual Environments, Felix George Hamza-Lup
Electronic Theses and Dissertations
Advances in computer networks and rendering systems facilitate the creation of distributed collaborative environments in which the distribution of information at remote locations allows efficient communication. Particularly challenging are distributed interactive Virtual Environments (VE) that allow knowledge sharing through 3D information. In a distributed interactive VE the dynamic shared state represents the changing information that multiple machines must maintain about the shared virtual components. One of the challenges in such environments is maintaining a consistent view of the dynamic shared state in the presence of inevitable network latency and jitter. A consistent view of the shared scene will significantly increase …
