Applications of Voronoi diagram on Facades /Comparative study of contemporary architectural projects/

This search aims to introduce the voronoi diagram, its history and its characteristics of space wayfinding, occupation analysis and space evolution. In addition to introducing the most important applications in architecture : urban planning , architectural design, landscape and even construction, and the benefits in terms of the effective and orderly division of the land and integration with nature and achieve tectonic. The search turns into studying the Voronoi diagram applications on facades by analyzing and comparing a range of contemporary architectural projects adopted Voronoi in designing facades, and is reached through the comparative study of Voronoi applications on facades to the standards in terms of function, form, construction and sustainability. Research concludes with a set of recommendations.

Building 3D Digital Models For Cities in Large Topographic scales in GIS

3D GIS can be realized as an actual building platform of the urban space. This research develops automated 3D urban models that fit large-scale digital photogrammetry. Originally, modeling used manual or semi-manual techniques, and there is a need to for a development of an approach that automates the transformation of vector linear data, optimized by digital photogrammetry stations to create the 3D volume model in 3DGIS. This approach consists of three main phases: roof modeling, wall modeling and volume structuring. During the first phase, local and conditional "Delaunay Triangulation" method is used to deal with the majority of roof types regardless of its geometry. The second phase is completely automated to create the walls by the vertical projection (Top-Down) of the outer line of the roof into the Digital Terrain Model (DTM), and then by the selection of the bottom base level as the default level. Finally, different elements of the structure can be aggregated using spatial relationships (many-to-many) already supported by GIS software. The new approach is created and completely automated. It doesn't require roof geometric-types library, which asserts the GIS is a valid platform to build, to view and to store 3D urban models.
