Matthieu Chavent (CNRS, Paris, France)In the last few decades, visualisation of molecular assemblies has evolved drastically from simple line representations to macromolecular surfaces. This evolution was enabled by improved graphics hardware with new capabilities. Here, we present a new type of visualisation extending the approach used in our MetaMol program 1 . This visualisation, implemented in the FvNano program 2 , enables the generation of high-quality images using a GPU (Graphic Processor Unit) accelerated ray-casting algorithm. As a result, it is possible to visualize molecular representations with pixel precision at any level of zoom. This method is promising for both the representation of huge macromolecular assemblies and for small molecules, without any loss in rendering quality. We have implemented a new visual representation using hyperboloids that smoothly link the atoms. This depiction works very well to interactively represent macromolecules containing up to a few thousand atoms. We are now improving our implementation for substantially larger molecular assemblies. 1: Chavent et al. “MetaMol: High quality visualization of Molecular Skin Surface” JMGM, 2008. 2: http://www.loria.fr/~chavent/metamol.htm
