The further de velopment of CyberCity has to include various applications of 3D scenes from the outdoor scenes to the indoor ones. In thispaper, some key techniques, such as data management method and dynamicalvisualization method for the outdoor and the indoor scenes, are discussed.The indoor scene is compared with the outdoor one.

It is indeed based on the property of colored materials to reflect, in a selective way, the colored radiations of light. The innovation is here based on a more subtle and more complete process, using the trichromy, i.e., all the possibilities of the white light, which is split in three primary radiations： red^een--blue. One can, indeed, animate a pigmentary surface by the alternate projection of these three colors, and thus reveal three different images on the same support, or create a motion effect. However, in this process, the weakness of bhie, compared to green and red, might constitute an obstacle. But that will be compensated by the use of fluorescent colors, instead of ordinary colors. This process may provide very spectacular applications in the fields of lighting, architecture, design, scenography, booths, display windows, etc.. We shall propose a step-to-step approach.展开更多

This paper has explored the used digital software and forms of artistic expression in this system, summed up the experience in the production of shooting, image stitching, and image post-processing as well ss art design, and finally combined with the Lingnan culture features to design the arcade naturalist city show platform.展开更多
