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.
Technical InformationThis simulation was performed using proprietary software written in Fortran running on a Silicon Graphics Personal IRIS 4D/25G workstation.
