地形可视化算法研究

近年来,随着计算机硬件性能的不断提高和相关算法的研究,地形可视化在三维游戏、飞行模拟训练、战场环境仿真、地理信息系统、虚拟现实等领域得到了广泛的应用。本文主要从构建地形网格、简化地形网格、计算对象空间误差和屏幕空间误差、视域剔除的实现等方面对地形可视化算法进行了深入的研究。最后总结并分析了地形可视化算法今后的研究重点。

Research of Terrain Visualization Algorithm

In recent years,along with the hardware' s performance unceasing enhancement of computer and correlateion algorithm' s research,at the 5D game.the flight simulation training,battlefield domains environment simulation.GIS. virtual reality,terrain obtained the widespread application.This article mainly from the construction terrain grid,the simplification terrain grid,computation object space error and screen space error,view frustum culling realization have the thorough research on the terrain visualization.Finally,summarize and analyze the terrain visualization algorithm next research key.
