This paper describes an approach for detecting windows from multi-aspect airborne laser scanning point clouds which were recorded in a forward looking view. Since the resolution of the point cloud is much lower than from terrestrial laser scanning, new methods have to be developed to detect and, in a further step, reconstruct façade structures. The façade planes are detected using point normals...

A virtual 3-dimension city model is a sophisticated application of geoinformatic systems as it represents layouts, activities and functionalities of a real-world community. To enable human users to better visualize their living spaces, a virtual reality city model must be both immersive and accurately re-created. Visualization of city models in such environments is a combination of many challen...

Very high resolution SAR tomography using multiple data stacks from different viewing angles enables us for the first time to generate 4D point clouds of the illuminated area from space with a point density comparable to LiDAR. They can be potentially used for façade reconstruction and monitoring in urban environment. In this paper, we propose an approach for façade detection and reconstruction...

This paper outlines a new approach for generating digital heritage models from laser scan or photogrammetric data using Historic Building Information Modelling (HBIM). HBIM is a plug-in for Building Information Modelling (BIM) software that uses parametric library objects and procedural modelling techniques to automate the modelling stage. The HBIM process involves a reverse engineering solutio...

We propose a system for generating high-quality approximated façade ortho-textures based on a set of perspective source photographs taken by a consumer hand-held camera. Our approach is to sample a combined orthographic approximation over the façade-plane from the input photos. In order to avoid kinks and seams which may occur on transitions between different source images, we introduce color a...

Recent studies have shown that the façade and light patterns in a space are an important factor occupants' experience, but little is known about generalizability of these findings different lighting conditions, uses space, or latitudes. This study employed virtual reality to investigate effects geometry daylight on impressions physiological responses (skin conductance, heart rate, rate variabil...

Designing novel interaction concepts for urban environments is not only a technical challenge in terms of scale, safety, portability and deployment, but also a challenge of designing for social configurations and spatial settings. To outline what it takes to create a consistent and interactive experience in urban space, we describe the concept and multidisciplinary design process of VR/Urban’s ...

In this paper, a new building concept for multi-family lightweight timber frame housing is proposed. This concept combines party walls, floors and façade elements ensuring comfort levels equal or better than currently encountered in typical Belgian heavy constructions. Low frequency behaviour and prefabrication potential were the key points in the design process of the new wall and floor types....

Façade is an artificial intelligence-based art/research experiment in electronic narrative – an attempt to move beyond traditional branching or hyper-linked narrative to create a fully-realized, one-act interactive drama. Integrating an interdisciplinary set of artistic practices and artificial intelligence technologies, we are completing a three year collaboration to engineer a novel architect...

High-rise buildings with a large proportion of transparent areas, where conventional external overheating protection cannot be used due to the wind loads, are often problematic from an energetic and comfort point of view. In this paper a glass façade system is examined, which controls the energy flows within the transparent building envelope. Two fluid-filled layers are implemented in a glass f...
