Visual Simulation of Tire Smoke

In recent years, the realism of video expression by 3DCG has increased remarkably. In this study, we propose a CG representation method of tire smoke based on physical simulation. Although tire smoke has appeared in various video works and 3DCG games, the mechanism of how tire smoke is generated has not been fully elucidated. We calculate the generation and conduction of heat from the rotation speed and friction between the tire and the ground, and construct a model of tire smoke generation from the viewpoint of statistical mechanics. The parameters in the mathematical model are set from actual images and observations, and we confirm that the phenomenon of tire smoke can be reproduced.
