基于LOD的大规模输电线路场景实时渲染算法优化
Real-time Rendering Algorithm Optimization for Large Scale Transmission Lines Based on LOD
摘要
Abstract
A LOD algorithm by simulating the characteristics of the human eye and based on multiple control factors is proposed which is used to solve the problem of the low efficiency of the large-scale terrain environment simulation for transmission line corridor.The algorithm comprehensively considers the distance and terrain factors to simplifv the terrain mesh,combined with the characteristics of the simulation scene mostly working in roaming mode.Moreover,in the evaluation function,the viewpoint movement speed is regarded as an important control factor.The optimized algorithm can simplify the calculation model of the evaluation function in the perspective of roaming state.The comparison experiment shows that the proposed algorithm has faster rendering speed than the ROAM algorithm and the restricted quadtree algorithm.关键词
