Remote visualization of dynamic molecular data using WebGL

Abstract

Visualization of dynamic data from molecular dynamics simulations is crucial for understanding the functioning of molecules. Many existing visualization tools have mainly focused on supporting a single user working on a desktop computer. Technical advancements in browser features increase the potential for the development of web-based collaborative visualization tools. Although web-based molecular viewers already exist, their support for dynamic molecular data at interactive rates is lacking. To address this gap, we present an efficient web application for visualization of dynamic molecular data using WebGL that exploits HTML5 technologies like WebSockets and Web Workers. We demonstrate the feasibility to visualize large dynamic molecular data in the browser at interactive frame rates. Moreover, the application can be employed for remote simulation monitoring on mobile devices. Our approach allows scientists at arbitrary locations to concurrently visually analyze the same data. The interactive parametrization of the visualization can be shared among multiple clients, providing the basis for collaborative research.
