| Abstract: | 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. |
