Abstract: A particle rendering method and system that can receive a selection of a shape and/or a motion of a particle or a selection or a correction of a predetermined particle pattern, and generate a particle corresponding to the selection thereby generating a particle that has the desired shape and motion. Furthermore, the method and system can render a large number of particles in real time by sorting a plurality of particles using a render group. The particle rendering system includes a receiving module to receive a selection on a shape or a motion of a particle, and a first particle generation unit to generate a first particle corresponding to the shape or the motion by calling information corresponding to the shape selection from a shape information module or information corresponding to the motion selection from a motion information module.
