Computer Graphic Simulation of Lightning Discharge. Brady, P. K. & Katsaggelos, A. In Unknown Host Publication Title, pages 127–131. IEEE, 1987. abstract bibtex Actual images of lightning are subdivided into cells. Changes in bolt direction across these cells form a sequence that is treated as a signal. The power spectrum of this signal is obtained and shown to be best characterized by 1/f noise. A Fourier-transform method for generating 1/f noise sequences from a random white-noise source is presented. Lightning branching is modeled by use of context-free L-systems and their graphical interpretation. Synthetic images of electrical discharge are generated using parallel rewriting graph grammars and a 1/f-noise tortuosity model.
