为了模拟固体燃烧时产生的火焰及其伴随的物质分解过程,提出一个实时的燃烧模型.为了在模拟速度和视觉效果间取得一个很好的折中,采用一套混合的网格模拟系统;整个空间的热传导过程在一个统一的框架下模拟,因此能够很好地耦合动态的火焰和燃烧的固体.提出了一个改进的燃面更新方案以及一个新的固体表面纹理映射算法,能够生成逼真的结果.还提出了一系列提高模型效率的加速算法.最终实时地模拟出了真实感的固体燃烧现象.%In this paper, we present a real-time combustion model to simulate fire phenomena with solid object decomposition process involved. To achieve a good tradeoff between performance and visual appearance, a hybrid structure of grids is employed in the model. Heat transfer is modeled in a compact framework, so the turbulent fire and the burning solid are well coupled. With an improved burning surface update scheme and a novel surface texture projection algorithm for its visualization,convincing results are produced. To increase the efficiency of our model, a few acceleration techniques are proposed as well. As a result, realistic solid burning phenomenon is well simulated in real time.
