    GPU-Accelerated Generation of the Molecular Surface
    (The Eurographics Association, 2020) Alhazzazi, Mousa; Hayward, Steven; Laycock, Stephen D.; Ritschel, Tobias and Eilertsen, Gabriel
    A variety of visualisation methods have been developed for displaying molecular structures. The solvent-excluded surface (SES) or molecular surface is one of the most popular and useful depictions as it helps to identify binding-site cavities. The molecular surface is particularly useful therefore for interactive molecular docking tools. Docking tools that incorporate molecular flexibility bring new challenges as the molecular surface must be recomputed in real time as the molecule changes shape in interaction with a ligand. Here we compute the SES by using a GPU-accelerated Marching Cubes algorithm which promises to lead to real-time surface generation for small- to medium-sized biomolecules undergoing conformational change.

    Treemap Literacy: A Classroom-Based Investigation
    (The Eurographics Association, 2020) Firat, Elif E.; Denisova, Alena; Laramee, Robert S.; Romero, Mario and Sousa Santos, Beatrice
    Visualization literacy, the ability to interpret and understand visual designs, has gained momentum in the educational and information visualization communities. The goal of this research is to identify and address barriers to treemap literacy - a popular visual design, with a view to improve a non-expert user's treemap visualization literacy skills. In this paper we present the results of two years of an information visualization assignment, which are used to identify the barriers to and challenges of understanding and creating treemaps. From this, we develop a treemap visualization literacy test. Then, we propose a pedagogical tool that facilitates both teaching and learning of treemaps and advances treemap visualization literacy. To investigate the efficiency of this educational software, we then conduct a classroom-based study with 25 participants. We identify the properties of treemaps that can hinder literacy and cognition based on the results from the treemap visualization literacy test. Results also provide further support for the use of our tool that had a positive effect on treemap literacy skills of university students.
