Abstract

A method for rendering lightning using conventional raytracing techniques is discussed. The approach taken is directed at producing aesthetic images for animation, rather than providing a realistic physically based model for rendering. A particle system is used to generate the path of the lightning channel, and subsequently to animate the lightning. A technique, using implicit surfaces, is introduced for illuminating objects struck by lightning.
