In this work we propose and realize methods to create seamless transformations that allow us to affect and change each of these three parameters individually. The resulting transitions give viewers a dedicated control of abstraction in illustrative molecular visualization and, consequently, allow them to seamlessly explore the resulting abstraction space for obtaining a fundamental understanding of molecular systems.We show example visualizations created with our approach and report informal feedback on our technique from domain experts.I.3.m [Computer Graphics]MiscellaneousScientific visualizationmolecular visualizationillustrative visualizationdedicated seamless abstraction.
