[DM5-3] Modelling 3D

Traditionally many GIS used 2D or 2.5 D data models, but in the last decade 3D modeling mainly in form of city models or in the context of Building Information Models (BIM): - Basic concepts of 3D modelling, edge, area, volume models - The workflow of 3D modelling, general aspects, choose of the proper model - Methods of 3D modeling - Principles of Constructive Solid Geometry (CSG) - Principles of Boundary representation (BR) - Principles of Voxel-beased modeling - Comparison of the methods - The concept of BIM, principles and purpose - City models, principles and purpose - Examples / applications
