| 摘 要： | 针对三维图形引擎中要生成具有相当真实感的场景的时候,由于场景本身的复杂性,要实现实时性较为困难。本文从场景的本身的几何特性入手,通过适当的方法来简化场景的复杂性,提出了一种动态的层次细节(Levels of De-tails)技术。通过实验表明本方法有良好的显示效果,同时具有较好的实时性,显示效果较好,且占用的存储空间不大。

| Abstract: | It is difficult to render vivid terrain real time in 3D-Graphic engine because of the terrain's complexity.This paper uses a proper method to simplify the terrain form the terrain's geometry characteristic,and proposes a kind of technique which is dynamic levels of details.The experiment result shows that it has good performance and real-time character,and uses little memory.It can fit the demand for animation in nowadays 3D-Graphic engine. |
