Abstract: In order to extend the utility of Web partslibrary, a novel idea which developed diversified Application Service Provider (ASP) graphics services based on Virtual Reality Modeling Language (VRML) models of the parts and components in partslibrary was proposed . The contents of graphics services were analyzed. According to the characteristics and structure of VRML model, the architecture for ASP graphics services platform based on VRML model was established. Several basic algorithms involved in some graphics services in the platform were discussed in detail. Based on these studies, a parts search engine oriented to VRML models in the partslibrary was developed, and an application case in the system was used to indicate the effectiveness of the system and the algorithms.

Key words: partslibrary, virtual reality modeling language, application service provider, computer aided design, graphics services
