摘要
探讨了宽广视野三维虚拟环境沉浸式漫游的系统结构和若干技术问题。系统使用多台微机及配套图形卡构成集群并行渲染,使用MPI(message passing interface)构成消息递送环境,使用开放源码的OGRE(open graph rendering engine)三维图形引擎进行场景渲染。实验证明系统开发成本低、效果满足应用需求,可广泛用于训练模拟、飞行再现、虚拟战场环境等视景仿真领域。
The design and implementation ofimmersive 3D virtual environment wandering system in the wild field of view is discussed. The clustered parallel rendering system consists of multiple PCs and the assorted graph accelerating cards, which uses MPI as the message passing platform and open source OGRE （open graph rendering engine） as the 3D rendering engine. Experiments demonstrated that this cost-effective and satisfying solution is expanded and applied in many visual simulation fields, such as simulative training, flight reappearance, virtual war field environment and etc.
