    In this article we propose a hybrid modeling system based on B-rep model and volume model to overcome the inability of representing volume information of modeling object in conversional feature based modeling systems. Using this hybrid representation, we can easily solve the visualization and mass property computation for designing objects with specified volume attribute. In this article we propos...

    With the demand of distributed designers to cooperatively design a single product, these designers need to simultaneously access a common database, which holds the geometric model and other information of the product. But frequently, their design will lead to invalid results. Therefore, it is very important to build a distributed model to coordinate these designers to ensure the consistency of the...

    Sharing data is an important aspect in distributed design environments and should be supported by an underlying system. Any synchronous access to data is conflict prone. Applying concurrency control and two phase commit are an option to be considered. But design processes also demand cooperation between the designers. Negotiation about actions on the product under design and the early exchange of ... View full abstract»

    Although they are being exploited by businesses in a variety of industries, current workflow systems are considered to be too rigid. However, it is difficult to construct a new workflow system from scratch, due to its complexity. On the other hand, meta-groupware is attracting more and more attention, in that it can be used to compose sophisticated systems. In this paper, we show how to implement ... View full abstract»
