VMD: Publication-Quality Ray Tracing of Molecular Graphics with OptiX
Abstract:
This session will describe the adaptation of the popular molecular graphics program VMD to support both batch and interactive ray tracing using NVIDIA OptiX, on computers ranging from laptops all the way up to large scale Cray XK7 supercomputers such as Blue Waters and Titan. We will describe the benefits of custom VMD-specific geometric primitives and memory layouts, and relate our experiences adapting the Tachyon CPU-based ray tracing engine used by VMD, to NVIDIA's OptiX GPU ray tracing framework. The session will present performance data for workstation and supercomputer class visualizations, integration of OptiX into VMD, interactive ray tracing, many example movies and visualizations, and avenues for further improvement.
