Model-based analysis and validation using simulation is a helpful tool in the engineering of complex systems. This paper presents a tool chain for the model-based architectural design of avionic fiber-optic networks. A recently proposed framework for simulation-based domain-specific tools is the basis for the development. It supports a model-based design workflow and offers a new 3D graphical user...
Topological relationships between spatial objects are an essential property of spatial objects. They are used for spatial analysis and query processing. In this paper, we first introduce an alternative 3D geometric model, called the prism model. The prism model is based on an extrusion method from 2D footprints of 3D objects. Then we study the correspondence between the 2D topology of footprints and...
Currently used 3D models, which are mostly focused on visualization of 3D objects and lack topological structure, have limitation in being used for 3D spatial analyses and applications. However, implementing a full topology for the indoor spatial objects is less practical due to the increase of complexity and computation time. In this study, an alternative method to build a 3D indoor model with less...
