基于粒子系统来描述自然景物，自然景物中的火焰的模型一直是各个领域中研究的重点，不均匀、不规则使火焰具有特殊性，为了保证火焰模型的实时性，本文采用纹理映射方法来增加计算机图形的真实感-Based on particle system to describe the natural scenery, natural features of the model of the flame has been the focus of research in various fields, uneven, irregular flame with particularity, in order to ensure real-time flame model, we use texture mapping method to increase photorealistic computer graphics
