This paper describes initial results of a 3D field topology analysisfor automating transfer function design aiming at comprehensiblevolume rendering. The conventional Reeb graph-based approachto describing topological features of 3D surfaces is extended tocapture the topological skeleton of a volumetric field. Based onthe analysis result, which is represented in the form of a hyperReeb graph, a procedure is proposed for designing appropriatecolor/opacity transfer functions. Two analytic volume datasets areused to preliminarily prove the feasibility of the present designmethodology.
