分布式三维实时漫游系统数据存储和调度方法研究

Discussion on the Topic of Data Storage and Scheduling in Distributed 3D Real-Time Walkthrough System

本文针对工作站多通道输出的分布式三维实时漫游系统 ,设计并实现了DEM和纹理数据的存储和调度方法 ,详细介绍了数据的分块存储 ,视点相关的可见区裁剪和细节层次的选择 ,并且介绍了预可见区数据的预调度和多通道输出可见区的分割。该方法能保证场景显示的平滑和连续性 ,能达到比较满意的帧率。

Aiming at distributed 3D real-time walkthrough system of workstation multipipe output, a data storage and scheduling strategy of DEM and texture data are designed and realized, in which data partition and storage are introduced in detail. In the method, not only view-dependent visible region culling and the choice of level of detail are discussed , but also the prefigured scheduling of the next possible visible region data and the partition of multipipe output visible region are presented. This method makes sure of the smoothness and continuity of scene display, through which a comparatively satisfied frame rate can be achieved.
