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.
