    VISUAL SIMULATION OF LIGHTNING
    (1993-12-01) Wyvill, Brian; Reed, Todd
    A method for rendering lightning using conventional raytracing techniques is discussed. A particle system is used to form a lightning channel, and particular attention is paid to simulating the appearance of the lightning, including the glow around the channel as well as the effect of the lightning as it strikes an object. An object struck will also appear to glow. This is achieved by using a scalar field from which both the glow and the model can be derived.
