VISUALISATION OF BUILDING MODELS

摘要

In an existing integrated building design tool, BSim2002, a 3D building model can be created. The model can be used for thermal simulation, but also for other purposes, e.g. for calculation and visualisation of the solar penetration into a building. The model can be exported to other programs, e.g. for daylight calculations and visualisation. Finally the model can be visualised using the OpenGL technology, which is an integrated part of the Microsoft Windows operating system, allowing the user to have a virtual tour around and inside the building. This paper describes how this approach has been implemented and shows some examples of the advantages, especially when dealing with complex models, compared to the normal wire frame views used in this type of programs.
