Research into the the representation of flames using CG has focused on flame representation. There has been little research into the relation between the flame and the burnig object. The burning object has been interpreted as the fuel resource, that is, the combustion root, or as an obstruction to the flame's motion. In this paper, we interpret combustion as deformation of both the flame and the objects and propose a CG representation method. The representation subject is the object which occured the shrinking deformation. Before our experiments, we observed actual scenes of combustion, then based on these observations, we represented the deformation and the color change. In this method, the burning object is modeled using 3D volume data, and the control parameters are set to these. The deformation and color change are represented by changing the parameters with cellular-automata and a heat equation. Our experiments showed that our method more realistically represents combustion and deformation, particularly of wood.
