Frequently, algorithms for 3D facade reconstruction extract high resolution building geometry like windows, doors and protrusions from terrestrial LiDAR and image data. However, such a bottom-up modelling of facade structures is only feasible if the observed data meets considerable requirements on the amount of detail and coverage. For this reason, within our work, the explicit reconstruction o...

Current Internet-inspired mapping data are in the form of street maps, orthophotos, 3D models or street-side images and serve to support mostly search and navigation. Yet the only mapping data that currently can really be searched are the street maps via their addresses and coordinates. The orthophotos, 3D models and street-side images represent predominantly “eye candy” with little added value...

In the last years more and more applications make use of 3d building models. Automatic reconstruction is essential for the acquisition and updating of the huge amount of data. For many applications it is useful to be able to transform the object representation automatically in order to generalize the geometry. For this task a structurally rich description of the object is needed. We presented a...

The utilisation preference of glazed facades in the hot regions is accompanied by serious environmental and economic impacts. Attempts are continuing to fulfil an optimum balance between minimising heat gains and maximising daylighting benefits; in an economical approach. This study was conducted in Egypt, where a real case study was investigated to evaluate the thermo-visual performance of a b...

This study investigated the distribution of the fraction of rainfall intercepted by the facades of buildings located in an urbanized area. We used the frequently used semi-empirical standard ISO-15927-3 to simulate Wind-Driven Rain on facades. The implementation of the Norm on a neighbourhood scale required a list of parameters, including building geometry and terrain characteristics. For the f...

The purpose of this research is to investigate the ability to redefine the components and indicators of popular architecture facades in contemporary architecture. The research method is content analysis and descriptive-analytic and survey with semiotic and Delphi technique. At first, popular architecture is analyzed using the descriptive and analytical method. Next, 14 components of the popular...

ABSTRACT A methodology for the metric reconstruction of the planar surface of facades of destroyed buildings using historical single-view photographs has been presented in this work. The methodology is based on using a-priori object properties like linearity, parallelism, perpendicularity, symmetry etc. in addition to information extracted from the photographs. The methodology involves the dete...

In this paper we report on a new system to augment a 3D block model of a real city obtained from aerial photogrammetry or aerial laser scanning with geo-referenced terrestrial data of the facades. The terrestrial images are acquired by a hand-held digital consumer camera. The relative orientation of the photographs is calculated automatically and fitted towards the 3D block model with minimized...

In this paper we propose a real-time rendering approach for procedural cities. Our first contribution is a new lightweight grammar representation that compactly encodes facade structures and allows fast per-pixel access. We call this grammar F-shade. Our second contribution is a prototype rendering system that renders an urban model from the compact representation directly on the GPU. Our sugge...
