Digital Libraries for 3D Documents
Recent improvements in 3D content generation techniques in terms of modeling tools and aquisition devices like laser scanners have led to a huge amount of available 3D documents. They play an ever increasing important role in various fields like architecture, engineering, design, games, movies or cultural heritage. Digital libraries for 3D documents are to handle the challenges that arise with this increasing amount of 3D data. They provide tools enabling the user to efficiently search for existing 3D content involving different types of queries and category browsing. Additionally, they must ensure an adequate presentation of the search results.
Apart from arbitrary 3D documents, the computer graphics group's focus in the area of digital libraries is on data related to architecture an to cultural heritage. In the domain of architecture, we are especially interested in content-based retrieval and classification according to the topology of buildings and according to the shape of objects. For documents related to cultural heritage, our main focus is on high-quality visualization and on similarity search based on material properties.
