Computer Three-dimensional View Of Three-dimensional Display Technology

Stereo display is a key technology of Virtual Reality. When 3D scene is displayed on plane screen, the 3D depth information is lost because of the 2D limitation of the plane display device. So we image the depth information and the location information only by show order and size of objects. This paper carries out systemic research on stereo display technology. The works and fruits are as follows:1. In order to set up foundation of whole task, the paper analyses and simulates third dimension theory which is the foundation of Virtual Reality system, such as matrix transform, texture, texture filter and levels of details.2. Before stereo display technology comes true on plane screen, stereoscopic images pair of 3D scene must be got. Based on stereo vision theory, projection arithmetic of two centers and model of two eyes, the paper proposes a model of two eyes. With the model we get perfect stereoscopic images pair.3. For the sake of watching the stereoscopic images pair, some stereo display technology and images display format are illuminated, which help to realize the project.4. With the personal computer and 3D glasses, the paper proposes a scheme of stereo display system. Moreover the paper implements the stereo display system using CREATOR and DIRECT3D. The system provides us with perfect 3D stereo display effect and can be used for architecture walkthrough, virtual battlefield walkthrough and so on.
