    Real-Time Rendering of Molecular Dynamics Simulation Data: A Tutorial
    (The Eurographics Association, 2017) Alharbi, Naif; Chavent, Matthieu; Laramee, Robert S.; Tao Ruan Wan and Franck Vidal
    Achieving real-time molecular dynamics rendering is a challenge, especially when the rendering requires intensive computation involving a large simulation data-set. The task becomes even more challenging when the size of the data is too large to fit into random access memory (RAM) and the final imagery depends on the input and output (I/O) performance. The large data size and the complex computation processing per frame pose a number of challenges. i.e. the I/O performance bottleneck, the computational processing performance costs, and the fast rendering challenge. Handling these challenges separately consumes a significant portion of the total processing time which may result in low frame rates. We address these challenges by proposing an approach utilizing advanced memory management and bridging the Open Computing Language (OpenCL) and Open Graphics Library (OpenGL) drivers to optimize the final rendering frame rate. We illustrate the concept of the memory mapping technique and the hybrid OpenCL and OpenGL combination through a real molecular dynamics simulation example. The simulation data-set specifies the evolution of 336,260 particles over 1981 time steps occupying 8 Gigabyte of memory. The dynamics of the system including the lipid-protein interactions can be rendered at up to 40 FPS.

    12DoF Interaction for Scientific Visualisation
    (The Eurographics Association, 2017) Turner, Martin J.; Morris, Tim; Sandoval, Mario; Tao Ruan Wan and Franck Vidal
    This short extended abstract investigates human-computer interactions in relation to a specific Six Degree of Freedom (6DoF) input device; described is the driver development and calibration required for a novel piece of hardware; and after initial user tests and a questionnaire of satisfaction, we consider areas for further research. This abstract concludes with a discussion of the design and use of dual-6DoF input devices and from feedback how new interaction modes will be exploited.

    Human-in-the-Loop Visualisation Architecture for Monitoring Remote Compute
    (The Eurographics Association, 2017) Turner, Martin J.; Nagella, Srikanth; Fowler, Ron; Allan, Robert J.; Pasca, Edoarado; Yang, Erica; Tao Ruan Wan and Franck Vidal
    This paper describes the timeline of use cases of large and remote display VEs (Virtual Environments), hosted by STFC (Science and Technology Facilities Council), which were linked to HPC (High Performance Computing) systems. Considered is the development and use in the last few years of putting the human back into the HPC loop and clarifying the main types of interaction and collaboration that have been re-explored. It describes a set of specific common modes of use as well as stages of development, categorising and explaining how best practice may be achieved.
