Continuous Levels-of-Detail and Visual Abstraction for Seamless Molecular Visualization

Julius Parulek, Daniel Jönsson, Timo Ropinski, Stefan Bruckner, Anders Ynnerman, Ivan Viola
2014 Computer graphics forum (Print)  
Molecular visualization is often challenged with rendering of large molecular structures in real time. We introduce a novel approach that enables us to show even large protein complexes.  ...  The rendering performance is evaluated on series of molecules of varying atom counts.  ...  Acknowledgements We thank Nathalie Reuter for providing the MD simulation data sets, David Goodsell and Helwig Hauser for giving us the necessary feedback for the overall visualization.  ...
