Adding shadows to particle systems can go a long way to improve visuals and realism. Our work is concerned with external shadows cast onto a particle system by an occluding object, for which shadow mapping is combined with the particle system in an implementation that uses the Graphics Processing Unit (GPU).10.2312/egp.20101030
