Its a very interesting IFC viewer, as it provides viewing options that are not generally found in a standard IFC viewer software.You can set transparency of objects and elements as full, partial, or none; this lets you view the outer portion as well as inner portion of a 3D model. An ...
Full size image Based on these descriptions, models could have been created in various manners of including duplications or flyweight arrangements. Considering models which are affected by duplication, we separate between geometries using model coordinates and geometries using world coordinates. When using...
rich set of building element definitions designed specifically to facilitate the unambiguous exchange of data between software applications. More important, the IFC model has been endorsed as a standard of the International Organization for Standardization (ISO) for use by industry stakeholders.(The full...

Full size image Graph representation of building-specific knowledge The topology (structure) of the building is stored in the form of a labelled and attributed directed graph. Each space (room, corridor, etc.) is represented by a node in the graph, while edges represent connections between the...
as an intermediate data model to combine IFC and CityGML classes and terminologies. In the same trend, Tauscher [37] introduced the Triple Grammar Graph (TGG) as an automated ontology tool for IFC2CityGML mapping rules. However, such an approach is mainly based on full semantics mapping and...
The 3D cadastre was introduced in order to overcome the difficulties of traditional cadastral systems with regard to registering and visualizing complex 3D situations [1,2,20]. There are several ways to introduce 3D geometry into a cadastral system, e.g., through a hybrid or full approach, or...
