Important Progress in Indoor-Navigation
Award for the Level of Detail-Modell (LOD) of the Beuth Hochschule
Berlin – 30. August 2010: In cooperation with the Beuth Hochschule, 3d-berlin presents a new concept for the Level of Detail (LOD) for 3D-Indoor-Visualization. As a result, significant quality improvements could be archived. “It’s not about archiving the highest level of details, but about the optimal level to transfer all relevant information to the visitor”, says Dr. Björn Clausen.
3D-Visualization for Indoor-Navigation
3D-Wayfinding has several advantages since the human brain can process the information and store them in a mental map. Scientific results have shown that the wayfinding with 3D-Animations is superior to common overview maps. Based on Virtual Reality, these findings can be used to guide visitors to their destination points, in the web, on the kiosk or on the smartphone.
„LOD–Model“ – striking three-dimensional Indoor-Visualizations
In science there are 4 stages of LOD for 3D city models. The buildings indoor model represents stage 4. The LOD model presented today consists of 3 more stages. This model is an approach to divide the different Levels of Detail of the interior design striking and logical. Variable parameter in the different levels affect the degree of realism of the virtual building: For exmaple the parameter “number and presentation of objects” can be “high” and in consequence very realistic. Or it can be “low” and in consequence has the advantage, that only the most important objects needed for the wayfinding , called “landmarks”, are shown. For example: turn left after the blue statue.
“By the use of Level-of-Detail-models we are able to achieve the visitor’s most learning success in wayfinding”, says dipl.-geographer und projectmanager at 3d-berlin Björn Gäde about the model’s advantages. “Humans orient themselves to so-called landmarks. They have a high importance in navigation and have to be identified to use them to support the navigation process” he continues.
The idea to use the Level-of-Detail-model came from Katharina Weber (27), former intern and current employee at 3d-berlin. Katharina Weber realized this idea in her thesis, which has been awarded by the Beuth Hochschule as best thesis in the area of Geoscience / Cartography. „The own education and training of our highly qualified joung professionals in our company is particularly important. Since the formation in 2007 we had several interns which are very talented and we are very proud of”, Clausen says.
3d-berlin’s Detail-Level-Concept reduces Complexity
„The Level-of-Detail-Model is a way to describe the varied possibilities of visualizations of buildings. Our customers, center and facility Manager do not have to be confronted with difficult terms like “polygons” or “shading-process”, but can decide by themselves which level of detail they want to have for their building”, Clausen explains. “Price and expense for the implementation of the 3d-wayfinding-system Guide3D is therefore very adaptable to the building”.
