Computer graphics technology nowadays can interactively display billions of atoms forming structures up to entire biological organisms such as bacteria or protista. The key insight that allows it is the following: while biology is immensely complex it is also very repetitive, which could be exploited in coping with complexity. Life forms are internally composed of evolutionary successful patterns that are frequently repeated. This repetition, or multi-instancing in our terminology, can be observed on every level of spatial organization. Thanks to such patterns, model construction of the entire life form can be efficiently parallelized and consequently displayed using fast rendering routines, where both stages are executed on the graphics hardware.
In terms of complexity, resulting scenes are of multi-scale, multi-instance, crowded, and dense three-dimensional nature. To effectively convey such complex structural arrangement, visualization algorithms need to cope with all of these structural characteristics simultaneously. This need triggers the necessity of novel visualization algorithms that can cope with very complex scenery in 3D occlusion management, color assignment, shading, textual labeling, or navigation.
Complementary to visualization challenges, a question arises how to model these complex structures efficiently. The key insight is that modeling has to support sequential, schematical and three-dimensional structural organizations and allow for modeling on all spatial scales the structure spans through. This leads to new ways how for example DNA-Nanotechnology machines are designed, which might be employed in next-generation medicine.
All these new algorithms lead to gradual democratization of computer graphics and visualization technology for structural biology and biotechnology. Ultimately, the advances lead into new exciting ways how biology can be explored, understood, and communicated in the future.
Ivan Viola is an associate professor at King Abdullah University of Science and Technology (KAUST), Saudi Arabia. In his research, Viola investigates methods that automate the visualization design process. Basal new technologies he then applies to various application domains, such as ultrasound diagnostics, geology, or submilimeter biology. Viola has graduated from TU Wien, Austria in 2005 and moved for postdoctoral fellowship to the University of Bergen, Norway, where he was gradually promoted to the rank of Professor. In 2013 he has been awarded a Vienna Science and Technology Fund grant to establish his own research group back at TU Wien, Austria. After several years of research on visualization and computer graphics techniques for conveying multiscale biological structures in Vienna, Viola has co-founded the startup company called Nanographics, to commercialize nanovisualization technologies. Currently, he has relocated to KAUST for taking advantage of generous research conditions to multiply his investigative efforts, for delivering technologies that make visual, in-silico life possible.
