摘要
森林场景的仿真是对复杂环境仿真中的重要部分。建立具有沉浸感、高逼真度的森林场景,除了高真实感的树木及花卉等植被,同时需考虑风效等影响森林场景逼真度的自然因素。为快速绘制具有真实感的大规模虚拟森林场景,围绕Virtools虚拟现实仿真平台使用树木三维模型进行实时交互的要求,制作插件结合SpeedTree树木软件绘制森林场景制作仿真系统,通过实验室仿真研究常见的风速模型分析比较,提出适合实时植被绘制的森林仿真风速模型,对应用风速模型的森林场景风效进行实验验证。
Forest scene simulation is an important part in complex environment simulation.To establish a forest sense with immersion and high-fidelity,not only the highly realistic trees and flowers and other vegetation are required,but also other natural factors affecting the forest scene fidelity need to be considered as well,such as wind effect.In order to render the complicated and large-scale scene of virtual forest rapidly,and around the real-time interaction required by plants three-dimensional model using Virtools as virtual reality simulation platform,we develop plug-ins and combine trees software SpeedTree to render forest scene and produce simulation system,and study the common wind speed models through laboratory simulation to make analysis and comparison,suggest the forest simulation wind model suitable for real-time vegetation rendering.Finally,the forest scene wind effect applying the wind model is verified by experiment.
