Description
Forest Fire propagation is simulated using fractal ellipsoids driven by
a heurisyic dynamic model. An elliptical region of fire is defined oriented
in a specified wind direction of the wind and is proportional to its speed.
Fire, smoke and trees are modeled with ellipsoids whose shading and translucence
are modulated by a 3-D fractal texture function, which simulates a naturally-
random Gaussian mass distribution in each ellipsoid. All smoke ellipsoids are
textured with the same pattern which moves downwind with the ellipsoids. Fire
flicker is simulated by moving a second fractal pattern rapidly over stationary
fire ellipsoids.
