图形引擎与物理引擎结合的研究与实现

摘要

The 3D virtual environment with physical characteristics has more realistic sensation for users, thus the physics engine has been getting more importance in the virtual simulation. This paper describes the OGRE graphics engine and the PhysX physics engine, and then designs the main framework for the bonding of graphic engine and physics engine. The core part of the process has been analyzed in detail, and the creating of model has been studied.Finally, two virtual scenes with physical characteristics are given. The research has established the foundation of the virtual simulation environment, and will promote the application of the physics engine.%由于具有物理特性的三维虚拟场景更具有真实感,用户更易于沉浸到场景中,因此物理引擎在虚拟仿真中的作用日益重要.首先采用了OGRE图形引擎和PhysX物理引擎,设计了图形引擎与物理引擎结合后的主体框架,对框架的核心部分进行了分析.然后在物理引擎中创建模型和用OGRE模型转换为PhysX模型,以及利用关节实现复杂模型.结果实现了两个具有物理特性的虚拟场景,为建立真实的虚拟仿真环境打下基础,并将促进物理引擎的应用.
