摘　　要：在视景仿真中,地形是影响显示速度的重要因素,地形的逼真度和显示的实时性是一对尖锐的矛盾,因此地形的快速渲染也成为研究的热点。该文从视相关角度探讨了一种视景仿真中大地形实时分层显示的方法。In visual simulation, terrain-data is an important factor which influences the render speed. The fidelity of the terrain and the real time display are a pair of conflict. So how to render terrain fleetly becomes a research hotspot. This article discusses a method by which to display a big terrain in real time. This method relates to 搗iew-point relative?and 揕evel Of Detail?
