User studies, evaluations, and comparisons of tree visualization systems have so far focused on questions that can readily be answered by simple, automated queries without needing visualization. Studies are lacking on the actual use of tree visualization in discovering intrinsic, hidden, non-trivial and potentially valuable knowledge. We have thus formulated a set of tree exploration tasks not ...

Deformation is a topic of interest in many disciplines. In particular in medical research, deformations of surfaces and even entire volumetric structures are of interest. Clear visualization of such deformations can lead to important insight into growth processes and progression of disease. We present new techniques for direct focus+context visualization of deformation fields representing trans...

The concept of visualization essentially refers to the use of visual or graphical techniques for presenting information. In computing, there is typically also a connotation of large amounts of information being presented in a more compact way through the mapping to visual dimensions. Visualization in computing is a large, rapidly growing and heterogeneous field and this presentation is not aime...
