• modelling knowledge templates
• reuse of primitive models
• reuse of 3D scenes
• reuse of modelling knowledge

This paper presents a knowledge reuse framework to solve the problem that modelling knowledge cannot be reused effectively in the process of generating multi-type railway scenes. We designed the contents and instantiation method of the modelling knowledge templates. Then, we discussed in detail how to parse the modelling knowledge templates Finally, we designed the scene mapping and instantiation method. We developed a prototype and carried out experiments. The experimental results show that our method is applicable to unified modelling of different types of 3D railway scenes on the same platform, enabling reuse of primitive models, 3D scenes and modelling knowledge.
