....Introduction The recent interest in three dimensional graph drawing has been motivating studies on how to extend two dimensional techniques to 3D space. Work in this direction includes extensions of simulated annealing techniques, spring embedder techniques, and incremental techniques (see e.g. [5, 9, 15, 22, 23, 28]) However, while a rich body of literature is devoted to three dimensional orthogonal drawings (see e.g. 3, 8, 14, 16, 17, 21, 23, 29] little is known on the challenging task of extending to 3D the well known topology shapemetrics approach [26] The topology shape metrics approach for ....

.... representation of graphs in the plane, and the most sophisticated of them also allow some three dimensional representation, either as an additional presentation feature of basically 2D results (see GMB [13] and PLUM [17] or as the result of an actual 3D drawing algorithm (see 3DSA [4] COMAIDE [6], the ffGraph library [9] GEM 3D [2] GIOTTO3D [11] GOLD [10] GOVE [18] and PARSA [14] The tool we describe in this paper offers to the user a general frame for the representation of graphs entirely devoted to 3D drawing algorithms, and especially to their evaluation, development and ....

....It uses a physical analogy, where a graph is seen as a system of bodies with forces acting among them. These algorithms seek a configuration of the system with, possibly local, minimal energy. Force directed approaches have been exploited in 3D graph drawing to devise the algorithms presented in [4, 6, 9, 19, 26, 14, 20]. Further, the research on straight line drawings stimulated a deep investigation on theoretical bounds. Examples of bounds on the volume of a straight line drawing can be found in [5, 21] Namely, in [5] it is shown that a graph can be drawn in an n 2n 2n volume, which is asymptotically ....

....to other spatial metaphors such as cone trees. 2 Related Work GIOTTO3D [8] is a system for visualizing hierarchical structures in 3D. It uses a technique combining 2D drawing methods with a lifting transformation that exploits the third dimension to visualize hierarchical relations. The COMAIDE [5] toolkit supports cooperative force directed layout management, concurrent with dialogue handling, for heterogeneous multi layered 3D interactive diagrams. In [3] interactive techniques for 3D visualizations are presented using the cityscape metaphor. In [2] selectively dynamic features are added ....
