This video demonstrates our real-time molecular visualization application written using OpenGL and GLSL. The video features three distinct visualizations: Stick-and-ball, Connolly surface and density plot. The application renders the molecule using image-based lighting combined with depth-of-field. Ambient occlusion and fog is further used to enhance the perception of depth. The Connolly surface can be dynamically recreated when changing the orbital or probe radius. When recreating the Connolly surface the ambient occlusion is dynamically updated. The density plot, which features five separate density fields, is composited onto the rasterized geometry using raymarching.
The application is part of a presentation which will be given at Symposium on Scientific Visualization held on September 25th – 26th, 2012 at The Royal Danish Academy of Sciences and Letters in Copenhagen.
