动态地形可视化算法-IDTRA
Visualization of dynamic terrain algorithm-IDTRA
摘要
Abstract
The visualization of dynamic battlefield mainly involves real-time rendering of dynamic terrain.Dynamic battlefield terrain simulation improves reliability and fidelity of battlefield environment simulation.This paper presents an improved dynamic terrain ROAM algorithm lDTRA,based on DEXTER-ROAM.IDTRA divids the view frustum culling processes in two steps:First step IDTRA using terrain blocks for coarse culling,and second using diamonds for fine culling.In consideration of shortcomings of current dynamic terrain visualization methods,this paper proposes a visualization system for three-dimension battlefield based on OGRE.A dynamic crater demonstration is given to verify the feasibility of presented algorithm.The results show that the IDTRA algorithm presented in this paper can satisfy the requirements of dynamic battlefield terrain simulation in both speed and effects.关键词
