    The Effects of Adaptive Synchronization on Performance and Experience in Gameplay
    (The Eurographics Association, 2019) Watson, Benjamin; Gavane, Ajinkya; Shrivastava, Rachit; Fusiello, Andrea and Bimber, Oliver
    As graphics (GPU) hardware has improved, fixed refresh rate displays became a significant throttle on graphics performance. GPU and display manufacturers therefore introduced adaptive synchronization (Async), which allows displays to adaptively synchronize to GPUs, avoiding rendering stalls and improving frame rate mean and variation. This research is a first experimental examination of the effects of Async on the experience of dedicated (but not professional) gamers. Participants played a first-person shooter (FPS) game, both with Async on and with Async off. After each game session, we assessed participant emotional state and gaming performance. We learned that at least for this popular FPS, Async can improve gaming performance, and may also benefit experience. We also found that Async has intriguing relationships to game familiarity and years of gameplay that merit additional investigation. Further research should examine these relationships, as well as Async's effects in systems with higher frame rates.

    A Projection Mapping System onto a Human Body for Medical Applications
    (The Eurographics Association, 2019) Fukuhara, Ryo; Kaneda, Kazufumi; Tamaki, Toru; Raytchev, Bisser; Higaki, Toru; Nishimoto, Soh; Sotsuka, Yohei; Fusiello, Andrea and Bimber, Oliver
    In breast reconstructive surgery where patient's abdominal fat and blood vessels are transplanted to the breast, it is very important to identify the course of the blood vessels inside the abdomen. In this paper, we propose a system for projecting blood vessels extracted from computer tomography angiography (CTA) on a patient's abdominal surface to support the breast reconstructive surgery. The proposed system detects the position and orientation of a projector automatically using an image captured by a camera mounted with the projector and is able to project the exact course of the blood vessels onto an abdominal skin from an arbitrary direction. An experiment using an abdominal model fabricated from patient's CTA data with a 3D printer demonstrates the usefulness of the proposed system.

    Visual-auditory Representation and Analysis of Molecular Scalar Fields
    (The Eurographics Association, 2019) Malikova, Evgeniya; Adzhiev, Valery; Fryazinov, Oleg; Pasko, Alexander; Fusiello, Andrea and Bimber, Oliver
    The work deals with a visual-auditory representation and an analysis of static and dynamic continuous scalar fields.We propose a general approach and give examples of dynamic and static objects representations related to molecular data simulations. We describe the practical application and demonstrate how the approach may help to track geometrical features.

    Visualization of Large Point Cloud in Unity
    (The Eurographics Association, 2019) Santana Núñez, José Miguel; Trujillo, Agustin; Ortega, Sebastián; Fusiello, Andrea and Bimber, Oliver
    Large point cloud rendering has become a very relevant topic on 3D graphics as scanners and other sources of 3D point data are nowadays available to companies and the general public. In this project, we propose an implementation of a point cloud viewer, designed for the full-detail visualization of virtually unlimited point clouds for their inspection on short ranges. This work presents the data structure and the LoD technique to achieve a real-time rendering of the model, making emphasis on the details of an initial prototype based on Unity.
