基于粒子系统的林火实时绘制研究及实现

Study and Implementation on Real-time Rendering of Forest-fire Based on Particles System

为了满足林火图像实时绘制的需求,在总结近几年国内外对粒子系统的研究及对林火的认识的基础上,提出了一种适合大场景林火实时绘制的新型粒子系统模型。该模型对传统粒子的属性定义、基本粒子的运动及基本粒子的绘制等方面均做了补充和改进,并且采用硬件加速纹理技术提高了绘制的效果和效率,应用结果表明,该模型可以实时绘制出效果逼真的火焰图像,此模型所采用的技术也适用于其他不规则物体(如:烟、云等)的绘制。

Based on research on the latest literature and the understanding to forest-fire home and abroad, we provide a new kind of model by particles system to real-time simulate and render the large-scale forest fire. In this model, we improve the traditional particle system in the attribute, the movement and the rendering method of individual particle. In addition, we use the hardware-accelerated texture technology to improve the effect and efficiency of rendering. Meanwhile, the technologies adopted in the model also can be applied to other fuzzy objects（ such as smoke, cloud and so on）.
