| 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 |
