XU Li-ming,JIANG Yu-ming(School of Computer Engineering,Xidian University,Xi’an 710071,China)  
Virtual reality is an important developing direction of simulation technology,and it can help to make decisions at city planning,environmental protection,war field simulation,campaign training,and so on.A virtual scene roamed randomly is a basic and necessary part in virtual reality.The run-of-mill approach of constructing a virtual scene was introduced and the pivotal technologies of terrain,sky,physiognomy,natural phenomena etc were discussed,and the realizations of roaming control and roaming assistant tools were given.The simulating results show that the virtual scene acquires satisfied effects in real-time and third dimension.
