5. Conclusions 
Computer simulation is a hot research field in computer 
science. It provides a novel environment for people to explore 
macro- and micro-world. It is also the superb stage of 
multi-media technology. However, to implement this technique 
perfectly, obstacles are on the way. Both speed and 
processing capacity of computer hardware are limited, and 
price of high quality display equipment is also excessively 
expensive. On the other hand, expense of software 
development is also out of tolerance. Many works are still 
waiting people to do.
