Research on Semantics in 3D Graphics and Spatial Applications
Traditionally 3D graphics software and spatial software (like GIS) are not well integrated with semantics. There are however several important applications where the semantics of the 3D objects or the spatial objects are important for retrieval, visualization, management, information capturing. This line of research explores systematic integration of ontologies in 3D graphics and Spatial data, and their use to provide advanced functionalities in applications that use them.
To this end, TUC/MUSIC has developed methodologies for enriching 3D graphics models with domain ontologies and describing the objects and their relationships with those ontologies. The applications are not only in semantic retrieval but also in visualization and in automatic graphics generation. Areas of applications include CAD designs, architecture, culture etc. TUC/MUSIC has also developed methodologies for creating and using semantic maps of 3D spatial information. Such information for example may be useful in the personalization of the maps based on the interests of the users, and in the automatic indexing of photos taken by a camera which cooperates with a GPS and compass device. This technology is also applicable in the automatic generation of interactive photos.
