Automatic building feature detection and reconstruction in IFC models

The flexibility of the Industry Foundation Classes (IFC) format makes it challenging to blindly rely on the data it stores. This is because, to allow its flexibility, the stored data in an IFC file can be missing, incorrect, redundant, or stored in vague ways while the file can still be considered format compliant. This missing reliability is an...

Tree Reconstruction from a Point Cloud using an L-system

Storing accurate models of complex geometries in a compact way has become an increasingly challenging issue, especially when dealing with large datasets. One of such datasets is Cobra-Groeninzicht's database of all trees in the Netherlands. In the gaming industry, a new technique is being used to generate tree models: the L-system. An L-system...

Water Entrance Kinderdijk: Conceptual design for the multi-functional use of a discharge sluice

The World Heritage Site Kinderdijk consists of a landscape of preserved 18th-century windmills and is a popular touristic location. The number of visitors is continuously growing for the World Heritage Site at Kinderdijk. Visitors arriving via the water network have to cross a busy road to reach the heritage site. This is an unsafe and...

Ciclo Sampa: A generalised bicycle network design applied to Sao Paulo

Nowadays the city of São Paulo has to deal with a lot of traffic jams. Extending the road network is no option and the public transport network cannot keep up with the capacity either. A solution must be found in another type of transport: cycling. The current bicycle infrastructure is not sufficient in terms of connectivity. In this research, a...
