摘要：This paper presents a general architecture of the large-area terrain simulation system based on a single processor PC. It provides methods of modeling, management and dynamic scheduling for large-area terrain, achieving a balance between image quality and real-time rendering. The Grid stacks methods are developed to manage the database. The AOI approach has been developed to dispatch the database dynamically in the browse. The kalman filter approach has been developed to forecast the observer's position to improve the fluency of the browse. The implementation is based on OpenGL, and the technology is based on MultiGen-Paradigm Vega P rime platform, which provide a developer interface for a special system
