Abstract:
Visualization of large scale 3D models has become an important part of the development cycle in many fields
like building design, machine design, construction and many more. Whether for design communication or
demonstration, it is necessary for the viewers to fully understand the different components of the model, their
proportions compared to each other and the overall design. A variety of augmented reality(AR) applications
have been created for overall visualization of large scale models. For tours inside 3D renderings of models
many immersive virtual reality (VR) applications exist. Both types of applications have their limitation, omitting
either important details in the AR case or the full picture in the case of VR. This paper presents a low-cost
way to demonstrate models using a hybrid virtual environment system (HVE), combining virtual reality and
augmented reality visualization. The solution is built using a fully occlusive head mounted display(HMD),
together with off-the-she
lf web cameras and a game controller for interaction. A proof of concept is created using
a commercial game engine, which is used in a subsequent case study. Based on this study, we demonstrate
the validity of our proposed system.
