As an emerging technology, 3D video has shown a great potential to become the next generation media for tele-immersion. However, streaming and rendering this dynamic 3D data in real-time requires tremendous network bandwidth and computing resources. In this paper, we build a remote rendering model to better study different remote rendering designs and define 3D video rendering as an optimization problem. Moreover, we design a 3D video remote rendering system that significantly reduces the delay while maintaining high rendering quality. We also propose a reference viewpoint prediction algorithm with super sampling support that requires much less computation resources but provides better performance than the search-based algorithms proposed in the related work.

In this demonstration, we present WiiView, a view control interface for 3D tele-immersive (3DTI) environments. This interface allows the user to intuitively manipulate the virtual camera and graphical objects in a 3D tele-immersive virtual space, thus significantly enhancing the viewing experience for users in 3DTI collaboration. We have used WiiView in a dance class for creative choreography in Spring 2008 at University of Illinois at Urbana-Champaign. It allows for great flexibility, usability, and portability, as the dancers reported. Furthermore, the interface has become an interesting creativity tool for digital choreographers, as it creates a new element in the design space when dancers control the virtual view change and perform physical body movement simultaneously.

The Tele-immersive Dance Environment (TED) is a geographically distributed, real-time 3-D virtual room where multiple participants interact independent of physical distance. TED, a highly interactive collaborative environment, offers digital options with multiple viewpoints, enhancing the creative movement composition involved with dance choreography. A symbiotic relationship for creativity and design exists between dance artists and computer scientists as the tele-immersive environment is analyzed as a creativity and learning tool. We introduce the advancements of the interactive digital options, new interface developments, user study results, and the possibility of a computational model for human creativity through Laban Movement Analysis.
