Meshes on Fire
|A new method for the animation of fire on polyhedral surfaces was introduced. With discrete straightest geodesics,
fire fronts can be evolved directly on the surface of arbitrarily complex objects. Multi-scale wind fields
and geometric quantities were used to simulate the tubulence and the dynamics of fire.
|The straightest geodesic curves were used as pathes for fire flames to propagate along on the surface. The straightest geodesic curve is an extension of a straight line onto a 3D surface.
|For natural look of turbulent fire, a windfield model was used: a combined sum of global wind motion and stochastic local turbulence
