Virtual environment walkthrough applications are generally enhanced by a user’s interactions within a simulated architectural space, but the enhancement that stems from changes in spatial sound that are coupled with a user’s behavior are particularly important, especially within regard to creating a sense of place. When accompanied by stereoscopic image synthesis, spatial sound can immerse the user in a high-realism virtual copy of the real world. An advanced virtual environment that allow users to change realtime rendering features with a few manipulations has been shown to enable switching between different versions of a modeled space while maintaining sensory immersion. This paper reports on an experimental project in which an architectural model is being integrated into such an interactive virtual environment. The focus is on the spatial sound design for supporting interaction, including demonstrations of both the possibilities and limitations of such applications in presenting and promoting architectural designs, as well as in three-dimensional sketching.
Virtual set environments for broadcasting become more sophisticated as well as the visual quality improves. Realtime interaction and production-specific visualization implemented through plugin mechanism enhance the existing systems like the 3DK. This work presents the integration of the Intersense IS-900 SCT camera tracking and 3D interaction into the 3DK virtual studio environment. The main goal of this work is the design of a virtual studio environment for post productions, which includes video output as well as media streaming formats such as MPEG-4. The systems allows high quality offline rendering during post production and 3D interaction by the moderator during the recording.
