Dynamic terrain data visualization using virtual paging in multi-threaded environment

Abstract

The realistic terrain visualization has been the requirement of many applications like flight simulator, land resource planning, fly-through etc. The requirement of real time frame construction for consistent performance has lead to development of numerous modeling & visualization techniques in past. In this paper, a novel-rendering algorithm is discussed based on tiled data modeling. It constructs the frame from 3D model of terrain in nearly constant time. The algorithm is well suited for handling large datasets using the virtual paging and thread level parallelism is used for rendering and selection of tiles. © 2011 Springer-Verlag.
