| 摘 要： | 随着人们对信息需求的不断攀升,大型展览会都开始同期设立网上展馆。为了解决不断扩大的场景规模和访问者对场景的高精度要求之间的矛盾,采用了合理的建模方法,如优化模型、LOD技术和预渲染方法,简化的碰撞检测模型和天气仿真模型等对大型虚拟博览会场景进行了有效优化。在不影响场景质量的前提上,有效地减少了系统硬件设备运算量,降低网上博览会的运营成本,同时增强了系统的互动性,使大型虚拟博览会的体验更加真实和生动。

| Abstract: | Large-scale exhibitions begin to set virtual exhibitions online to meet the information requirement of people all over the world.Virtual scenes are becoming bigger and bigger,but the demand for finesse has not decreased.Reasonable modeling methods such as optimization models,LOD technology and pre-rendering methods,simplification models for collusion detection and weather simulation are adopted to reduce the calculation mounts under the condition of maintaining quality in order to reduce the operating costs... |
