Item Automatic architectural 3D model generation with sunlight simulation(The Eurographics Association, 2006) Mas, Albert; Besuievsky, Gonzalo; Pere Brunet and Nuno Correia and Gladimir BaranoskiNowadays, 2D architectural design is provided with many good tools. But it lacks efficient tools that could help designers in early stages of a project for tasks such as virtual prototyping or 3D model simulation. The 3D model generation from 2D floorplans in general implies tedious manual effort. With a 3D model the designer could validate both the building structure and the space distribution. Natural lighting is also a basic feature in structures design as a correct sizing of the building openings allow a better exploration of daylight illumination, and consequently, could prevent artificial illumination needs. In this paper we present a tool that allows to obtain, in a highly automatic process, 3D architectural models from 2D floorplans. The system also provides sunlight simulation for visualization and interactive edition operations. It allows to re-model the openings of the structure with real-time sunlight visualization. The whole module can be integrated within a standard CAD architectural platform as a complement for fast virtual prototyping and validation designs in an early stage of the project. We present results showing its application for both conceptual designs and for a real building model.
