Research on family of blend object
自由曲面对象族研究

The blend features contained only geometric information on conventional Breps is inefficient. This paper proposed a new method to describe blend features, which built family of blend object based on declarative family of object model. The blend features, based on high-level semantic information, could be added to a model containing relations between all features in the model. It defined constraints to specify important semantic information, and maintained the semantic information during the whole modeling process. Experiments implement describing blend features at a parameterized level and demonstrate its feasibility.
