OSG的视景漫游技术研究
Research on OSG Scene Roaming Technology
摘要
Abstract
With the development of virtual reality technology,a large number of open source and commercial graphics engine are launched.OpenSceneGraph (open source 3d graphics engine) is paid more and more attention by simulation users both at home and a-broad.Virtual scene is a crucial part of the application of virtual reality technology,and the scene roaming and collision detection are the core technology of virtual scene,which affect the authenticity of the whole virtual scene.We discuss the basic characteristics of OSG,the core library and its structure in the paper.Combining Visual C++ programming language,we realize a virtual campus model and analyze its roaming design.The observation and operation of an object from different angles,distances and azimuths gives the user the effect of immersion.At the same time,by the line of intersection collision detection method,we simulate the process of students stopping collision to prevent passing through an object when they encounter obstacles.By OSG technology,the requirements of 3D scene rendering to hard-ware and the developing difficulty are obviously improved.关键词
