摘要
针对水闸的启闭动作和出流过程，着重研究了基于语义的三维交互技术，包括语义交互建模和实现。语义交互建模从广义建模出发，定义了水工建筑物的物理和交互对象的语义模型，其中物理模型实现了建筑物物理特征的BNF描述，语义模型实现了按钮、闸门和水流对象交互任务的形式化定义，通过语义建模从整体上提出一个水利工程建筑物建模的语义交互框架，并研究了交互语义的实现方式，在此基础上，以水闸建筑物为例，给出了水闸运行控制仿真和三维效果的创建过程。
According to open-close operation and outflow course of water sluice, the thesis places emphasis upon semantic three-dimensional interaction technology, including semantic interaction modeling and realization of semantic interaction. Semantic interaction modeling gives definitions to physical model for hydraulic structure and semantic model for interaction object based on generalized modeling.The physical model realizes BNF description about structure physical characteristics, semantic model realizes formalization definition of button interaction task, gate interaction task as well as waterflow object interaction task. Through semantic modeling, the author puts forward a semantic interaction framework for one water resources engineering structure, and makes a study on realization methods for semantic interaction. Finally, the author presents the establishment of simulation on operation control for water sluice and its three-dimensional effect.
