This paper puts emphasis on the pivotal technologies of terrain,sky and building in constructing a virtual lafarge cement factory,including redundant modeling data simplification,texture mapping,multiple LOD models and the picking,bump check in real-time roaming by Vega.

The solution to a series of key tech-niques is discussed such as the modeling method based on Creator,Vega application environment,bump check,the development of visual simulation software and the implement of whole system.

Aimed at the major difficulties for developing a machine virtual layout system,this paper addresses the key theories of the virtual workshop modeling,virtual navigation,collision test,and the system development in phase.
