| Abstract: | The real-time rendering and walkthrough of three dimensional terrain has wide application area, and it can be observed in different view interactively by walkman. This paper presents the study and implementation of a real-time walkthrough system with personal computer. It adopts a real-time rendering algorithm based on overlay techniques. The system implemented the stereoscopic display and a convenient user interface. The system can naturally reach a balance between the quality of the image and the speed of the rendering. |
