OSG中三维场景构建的关键技术

随着基于OpenGL的各种三维渲染引擎的日趋成熟,如何更好地利用这些引擎已成为人们首先要解决的问题,而OpenSceneGraph作为一款高性能的、开源的渲染引擎也越来越受到人们的关注。系统地对OSG的结构和特性进行了分析,并对OSG中三维场景的构建过程以及其中的一些关键技术如三维场景的数据组织、场景的裁剪技术、渲染的流程等进行了研究。

Key Technology of Generating 3D Scene in OSG

With the development of various 3D rendering engines based on OpenGL,the full use of these engines has become the most primary problem.OpenSceneGraph,rendering engine of one high performance,open source is also paid people’ more attention.This article systematically analysed OSG structure and feature,studied construction process of 3Dscence and some key technologies with OSG.
