摘要

多细节层次描述（简称LoD）是实时绘制复杂几何场景的一种有效工具。基于层次结构的动态简化方法能够根据视点的变化，实时连续地转换场景细节模型。本文提出了一种改进的动态网格简化框架，它利用顶点映射机制支持不同细节层次之间的快速连续转换，同时还给出了建立和维护复杂场景动态简化层次结构的方法。

Abstract

Level of detail(LoD) representations perform an effective tool for real time rendering of complex geometric environments. Of these representations

hierarchical dynamic simplification can continuously refine a LoD model at run time according to changing view point. This paper improves original framework of hierarchical dynamic simplification. We apply a vertex mapping method to effectively support the rapid transformation between different LoD models. In addition

the method for constructing and maintaining the framework of hierarchical dynamic simplification is introduced.
