The document discusses several 3D modeling standards including BReps, CSG, primitives, DXF, SHP, VRML, X3D, KML, Collada, WebGL, O3D, CityGML, and IFC. It provides details on each standard's capabilities such as supported geometry, attributes, visualization options, and whether they enable semantic representation of 3D objects and linking to external data. The key points are that CityGML and IFC standards have added value through their representation of semantics while other standards focus more on visualization and exchange of 3D geometry.
