hl this paper , we propose a method to simulate sliding and falling snow by usj皿 g pa 血 cle method . By setting the density distribution of snow accordhlg to a research result on snow , and chang 量 ng the spring f () rce between particles depending on the density distribution , we express the diVision of snow . As a resulち we have confirrned that the division and falling behavior of the simulated snow is similar to the real one by comparing the simulation results and a movie on real snow .
