Abstract: We present a novel unified framework for simulating burning phenomena of thin-shell objects such as paper, cloth, etc. A gradient-based spreading model is proposed to simulate the movement of fire on thin-shell objects. To simulate the crumpling and deformation of thin-shell objects when burning, we present an FFD-based deformation model which takes the physical theory of burning phenomena into account. The fire is rendered by the method of particle systems. By inputting different parameters and initial conditions, our framework can simulate various burning phenomena of different thin-shell objects. Experiments validate that it is efficient and easy to implement.
