基于OpenGL的雪景视景仿真设计与实现

Design and Implementation of Snow-covered Landscape Visual Simulation Based on OpenGL

应用OpenGL进行雪景视景的仿真设计,模拟包括雪花飘扬、大地上产生积雪、大雪覆盖效果与观测视角转换的可视化实景,实现出相应的雪景视景仿真效果图。论述了虚拟现实技术、三维雪景可视化的仿真设计过程、处理雪花落地对地面产生积雪效果的解决方法、以及通过设置观测壶以窗口形式多角度观测大雪覆盖效果问题。最后对模拟实际自然环境下多种气象视景混合性问题提出展望。

OpenGL is used for designing of Snow visual simulation.Simulation includes the snowflakes,snow blanketing effect on earth and observational perspective transformation visualization.The implementation yields corresponding landscape visual rendering.The paper discusses virtual reality technology,real landscape visualization of three dimensional simulation,design process of snowflakes falling to the ground,effect of snow on the ground.The observation is by setting the pot in the form of window to implement thesnow multi-angle observation.Finally,it puts forward the visual mixed problem of simulated natural environment meteorology.
