关于改善可视化仿真系统实时性的途径

实时性是设计可视化系统所面临的关键技术问题之一,如何协调系统的实时性和模型的真实性是可视化仿真系统实现的瓶颈。结合应用仿真建模工具MultiGen的开发经验,从模型数据的组织结构、绘制优先级的确定,以及复杂场景建模与显示中常用的实例化、LOD、Billboard等方面,探讨了在可视化系统设计中改善实时性可采用的途径,并逐个分析其特点、利弊及处理技巧。

On Approaches to the Improvement of the Real-time of a Visual Simulation System

Real-time is one of the key technologies in the designation of a visual system,as well as coordinating the system's real-time feature and models' reality,which is known as the bottleneck.On the basis of development experience with MultiGen,a famous real-time modeling tool,not only are effective approaches proposed for real-time improvement in a visual system but also the characteristics,merits-and-drawbacks and techniques of each are discussed from the point of view of model data structure,drawing priority,and technologies for complicated scene modeling like instance,LOD and Billboad.
