摘要：The management of the open-air museum Ballenberg with about 100 original century-old buildings from all over Switzerland plans an attractive new overview map and a 3D information system of the museum area and exhibits. In this paper we investigate how highly detailed 3D terrain and building models can be utilised as base data for a flexible interactive 3D information system. The system shall be usable as source of information for museum visitors as well as an interface to more complex information for the Ballenberg management and architectural researchers. The integration of information in a 3D information system has to take into account that the user is able to freely navigate through the 3D model but nevertheless is limited by the fact that the 3D environment is projected onto a 2D screen. The presentation of additional information within a 3D environment might interfere with depth cues which allow perceiving the landscape model as close to reality and in 3D. The project employs a prototype to conceptualise and discuss the possibilities for inclusion of different types of information and media in a 3D environment. To create an effective interface to the different information contained we also explore how 2D and 3D presentations can be combined side by side or nested. The interaction with 2D and 3D objects on the screen with the help of commonly available input devices such as the keyboard and the mouse is discussed and methods for information linking and retrieval are suggested
