    Namako 2: Unity Plugin for Stress Visualization, Deformation Prediction and Haptic Rendering of Soft Objects
    (The Eurographics Association, 2025) Sase, Kazuya; Chen, Xiaoshuai; Tsujita, Teppei; Konno, Atsushi; Garro, Valeria; Young, Gareth; Elwardy, Majed
    Developing real-time deformable-body simulation with physical accuracy inside game engines remains challenging due to limited official support and integration complexity. To address this, we present Namako 2, an extended version of our previous Unity plugin that enables real-time finite element simulation with automatic mesh generation, 3D model embedding, robust contact handling, and built-in stress visualization. We demonstrate several example scenes of surgical simulation using Namako 2. The plugin is publicly available at https://github.com/sasekazu/Namako

    Perception of Visual Realism and Acuity in Real vs. Immersive Virtual Reality Scenes
    (The Eurographics Association, 2025) Huang, Nan; Hu, Yan; Sundstedt, Veronica; Goswami, Prashant; Imran, Muhammad; Lundgren, Anders; Garro, Valeria; Young, Gareth; Elwardy, Majed
    With the significant developments of extended reality (XR) technologies, the evaluation of the fidelity and practical applicability of immersive virtual reality (IVR) in replacing real-world shopping tasks is becoming increasingly important. In this paper, a virtual environment (VE) was used with a state-of-the-art head-mounted display (HMD) to evaluate participants' visual perception of IVR compared to reality. A visual acuity test demonstrates that in the IVR, participants experienced a significant decline of 37.1% compared to their real-world eyesight test score. Additionally, participants were asked to compare real furniture with their counterparts in an IVR, to complete Likert-scale questions assessing their perception of visual realism. This study initially reveals that IVR has the ability to convey the basic visual information of displayed virtual furniture objects.
