Abstract:
In recent years, Interoperability between Building Information Modeling (BIM) and Geographic Information System (GIS) model brings a strong demand in different domains. A number of researches and tools have been developed to integrate these two fields. Two most prominent standardized data models in BIM and GIS are IFC and CityGML. The conversion from IFC to CityGML in geometric and semantic perspective lay the foundation for the integration of BIM and GIS. This paper proposed a method for filtering of IFC objects and a rule for semantic mapping from IFC to CityGML and the experiments demonstrate the feasibility of the proposed method.

Abstract:
Industry Foundation Classes (IFC) has been known as an international common product model for Building Information Model (BIM) exchange and sharing in building field. With the purpose of solving the problem of model sharing between structural design and other application followed, the IFC is introduced into the structural working drawing field. Combining the demand for data description, an IFC extension model was established through entity extension and property extension. The extension model was verified by BIM-based structural drawing design prototype system in a test project. The research shows that extended IFCs is suitable for BIM model description in structural working drawing. Automatic model exchange is realized between structural working drawing and quantity survey by the extended IFCs.

Abstract:
Morphology is a new basic theoretical subject created in recent years. The architectural design naturally has the "priority of morphology" as a modeling art developed from design concept for moulding substance shape and space. Mathematics is also a kind of culture, and geometry is the best language describing the natural phenomenon and rule. The thought and method of contemporary architectural modeling are breaking through the constraint of traditional concept of Euclidean space, and it starts creating with manifold. This paper discusses the geometric modeling of immersion of classical 2D non-orientable manifold in E3 from the perspective of geometry. The creations of several classical digital building forms at home and abroad are analyzed, and it also provides the 3D demonstration on Rhino platform by NURBS technology. It focuses on presenting the immersions of various classical Klein bottle and real projection plane in E3.

Abstract:
Coefficient method and sunlight assessment are two major approaches to calculate building interval. The algorithm based on equal sunlight duration time (ESDT) principle and models can be used to calculate a legitimate spacing distance, according to sunlight on reference days. Relations of four key variables including the N-S ESDT distance, building facade, elevation difference of obstructive and overshadowed building, and the threshold of building's height are concluded from simulation tests and mathematical analysis. The ESDT technique combines convenient computation with precise analysis so that the algorithm is perfect for building interval calculation without setting up CAD models.
