基于OpenSceneGraph的大场景三维浏览系统设计与实现

Design and implementation of 3D large scene browsing system based on OpenSceneGraph

文中主要研究了基于OpenSceneGraph的大场景三维模型的建立、三维浏览系统设计与实现。首先在3DMax中建立场景中的独立模型,利用VirtualPlanetBuilder建立场景DEM模型,最后利用Visual Stidio和OpenSceneGraph设计并开发了大场景三维浏览系统,实现了三维场景模型的加载、浏览和漫游功能。

In this paper, the establishment of 3D model of large scene and the design and implementation of 3D browsing system were mainly studied based on OpenSceneGraph. Firstly, the independent model in the scene was established in 3DMax, and the scene DEM model was established by using VirtualPlanetBuilder. Finally, the large scene 3D browsing system was designed and developed by Visual Stidio and OpenSceneGraph, and the loading, browsing and roaming functions of the 3D scene model were realized.
