The Implementation of Virtual Roaming Technology
Abstract: Virtual Roaming Technology is a virtual reality interaction based on panoramic images, through a combination of virtual simulation and visual technology is extended to construct a virtual reality system, to carry out a full range of interactive display of the real scene, to provide all kinds of real-time interactive for the user, to a new type of modern technology of three-dimensional virtual roaming. This technology, will completely change the traditional browsing mode, to solve the complicated traditional 3D virtual display, break through the limitations of the plane, so that the user can be more effective, convenient to be personally on the scene roaming, more feel the scene sense of space, the effect of design, so as to realize virtual roaming the real strong, forming a three-dimensional scene visualization effect of the user interactive strong virtual and reality fusion. This topic using the 3D virtual technology openness, sharing, interactive, hypermedia, large capacity of the five major characteristics, and virtual reality interaction with multi-sensation, the existence of the four characteristic, interactivity and autonomy, the real scene based on panoramic images, two-dimensional angles, showing 3D perspective. In this paper, the primary research how to computer graphics and computer vision technology, the real environmental performance accurately in the virtual environment, and interaction design, making the real environment and virtual objects superimposed on each other, complementary information, exist at the same time, to solve the problem of how to enhance the real picture of performance, further blurring between the virtual world and real world computer generated line, give a person with real, intuitive, rich three-dimensional real scene. Secondly, in the aspect of technology, how to solve the real image of tissue forming the panorama, the use of Flash in the class package, written in Flash script language to realize the effect of 3D combined with Flash 3D engine, PV3D (PaperVision3D), to realize the panoramic picture of real-time interactive animation function, so that the user can roam between a plurality of viewpoints, to provide a friendly interaction, convenient and beautiful operation interface for users.
