3DH is a 3-year pilot project funded by Hamburg’s Ministry for Science and Research. It focuses on the dynamic visualisation and exploration of Humanities data from a DH perspective. The 'third dimension' of the 3DH approach is not necessarily conceptualized from the point of the traditional, i.e. spacial z-axis of physical objects, but rather as an expression of the semantic and hermeneutic 'depth' which characterises humanistic phenomena. The major goal is to establish a methodological and theoretical orientation as well as to develop prototypes of visualisation tools as demonstrators.
