| summary |
With the rising meaning of architectural lighting also the requirement at appropriate light planning rises. The possibilities of digital instruments were realized by several lamp manufacturers, which use 3D-CAD to present visualizations and use the Internet for their distribution. However in the field of universities it is important to offer instruments and methods with which the interaction of light and architecture can be learned descriptive, comprehensibly and interactively. Introductory in a theoretical section the bases of light planning and learn-educational concepts are pointed out. Parallel the state of the art in the areas of computer-aided learning and the light simulation is presented and evaluated regarding the learn-educational suitability. Thereupon an action requirement is formulated, which designates a new integration of the individual areas. It flows into the development of an interactive Web-based training system for the design with light - I-Light - whose concept and implementation in the following sections is described. In an application of examples the author points out finally, how this innovative connection of the Internet, 3D-CAD and simulation supports a better understanding of the medium light in the architecture perception. A new virtual light laboratory forms the core of this training system, in which architectural planning examples can be represented three-dimensional and changed interactively. A developed semantic scene model ensures for the fact that lighting, materials and delimitation surfaces are varied didactically appropriately and compared, so that visual effects and important interrelation can be assumed and checked. The author orients itself at the methodology by simulation and merges 3D-CAD and light simulation programs into the training system. The calculated photo-realistic picture is regarded not - as otherwise usual - as presentation material, but as interactive tools. Since 3D-CAD and light simulation programs presuppose much application knowledge, the author does not pursue to confront the user with these complex programs. He developed a new system with a Web-based graphic surface, that enables 3D-scenes to be loaded, be changed and stored easily (front-end). Furthermore it enables the remote control to an automatic, photo-realistic simulation on push of a button on an external high end render machine, that is connected via Internet, where at least all files are externally stored. For the operation of the front-end is only an average PC with a standard Webbrowser necessary. For the receiving station the author develops a new interface, which extends a standard Web server by the new possibility of storing and executing lighting simulations (back-end). The system presented by the author differs in the didactical concept and in the technical implementation from the solutions existing so far in similar areas. The interactive virtual light laboratories of the architectural planning examples represent a new beginning of Web-based learning environments. To the selected tools (HTML, Java, VRML, Web server, Lightscape) there yet exist no matured alternatives. |
