摘要
太阳风是从恒星上层大气射出的超声速等离子体带电粒子流。粒子系统被认为是模拟不规则模糊物体最成功的一种图形生成算法。在总结前人的基础上,提出了一种基于GPU的太阳风粒子系统的模拟。根据太阳风粒子的物理特性,同时受到电力和不均匀磁场力的作用,通过GPU算法进行实时渲染,动态模拟出太阳风爆发时的具有较强真实感和实时性的画面。
Solar wind is supersonic plasma electrically charged particles which are emitted from the upper atmosphere of the stars. Particle system is considered to be the most successful graphics generation algorithm which is used to simulate the irregular fuzzy object. On the basis of the predecessor＇s experience, this paper puts forward a simulation about solar wind particle system basing on GPU. According to the physical properties of solar wind particles, by electric power and asymmetrical magnetic field force at the same time, perform real-time rendering by GPU algorithm and dynamically simulate picture with strong sense of reality and instantaneity when erupting solar wind.
