3D Building Generalisation and Visualisation

The advances in the automatic acquisition of 3D geospatial data has lead to large-scale urban landscape models that can easily consist nowadays of thousands of building objects. For a photo-realistic visualisation, each building model has a number of highly detailed façade textures associated with. Because of the vast amount of objects and façade images, a brute-force rendering approach is not ...

3D Building Generalisation

The article presents a novel approach for the automatic generalisation of 3D building models with regard to the cartographic visualisation of urban landscapes. Building objects are geometrically simplified for the purpose of levels of detail generation to speed up rendering and to improve the perceptibility on small displays commonly found in mobile devices. Generalisation is realised in a proc...
