The application of conventional training methods displays many disadvantages particularly for highly complex equipment. Significant improvements and cost reductions can be achieved by means of three-dimensional computer visualization and animation of technical scenarios.

This paper identifies with a list of common problems which will be improved in the Virtual Training environment. The main idea is to develop a general modeling methodology that can be utilized in a wide variety of scenarios, while minimizing the need for programming simulation source code. The different layers of information used to define a training scenario are then described in detail. Both the author's view and the trainee's view of the developed prototype are presented.

Finally, the paper concludes with a description of the goals of a most recent research project which will adapt these scenario structures for utilization in an Augmented Reality environment.
