Abstract:

 In order to enhance the research and development of the particle system in teaching and practice of 3ds Max, a method was put forward  to use dynamic map and field of force to control the particle emissions and the relation was researched. The method  makes the geometry gradually becoming transparent from left to right, that is disappearing through the production of black and white dynamic map in control of the launch location of particles,and makes the particles flying all over the sky through setting field of force on the particle system， such as gravity, wind, force,PBomb，so it make the particle to be fantasy. Through designing the desertification words,it concludes that dynamic map controls geometry disappearing and sets the location of the particle,the field of force controls the state of the particle launching, the three constraint and affect each other.

Key words: dynamic map, particle flow(PF) particle system, field of force, spatial warping
