The presence of tunnels in protein structures substantially influences their reactivity with
other molecules. Therefore, studying their properties and changes over time has been in the
scope of biochemists for decades. In this paper we introduce a novel approach for the
comparative visualization and exploration of ensembles of tunnels. Our goal is to overcome
occlusion problems with traditional tunnel representations while providing users a quick way
to navigate through the input dataset and to identify potentially interesting tunnels. First, we …
