GLOBAL ILLUMINATION ALGORITHM USED IN COMPUTER AIDED ARCHITECTURAL DESIGN PRESENTATION

摘要

This paper presents a new, advanced approach to architectural design sharing, collaboration and presentation with a global illumination (GI) algorithm. At the early design stages the openings and the artificial lighting systems are not yet created in the building information model. Without the GI engine the interior spaces would not be visible for viewers. The GRAPHISOFT BIM Explorer (BIMx) is free, innovative, interactive, BIM viewer tool for architects setting new standards for design communication and presentation in the AEC industry. BIMx not only presents the building design but also provides an intuitive and interactive way to explore it. The interactive models can be distributed using conventional file sharing methods, or can be published on the BIMx community portal as well as shared via the private cloud service. All stakeholders can benefit from the interactive BIMx models using the most popular desktop, tablet and smart phone operating systems.
