Exploration of porous structures with illustrative visualizations

► The analysis of porous structures can be enhanced using a graphical model. ► A volume model of the structure alone is difficult to explore. ► The combination of a graph connectivity and a volume model provides tools to efficiently explore pore structures. ► The use of illustrative techniques such as cut-away, ghosting, edge enhancement and colormaps provides clues on the pore size and the topological distances between pores.
