    Experiencing High-Speed Slash Action in Virtual Reality Environment
    (The Eurographics Association, 2022) Yamamoto, Toranosuke; Fukuchi, Kentaro; Theophilus Teo; Ryota Kondo
    When a user uses a hand controller to swing a virtual sword in a virtual space, the sword movement seems slow if the its trajectory reflects the input directly. We hypothesize that this is because we are accustomed to seeing fast and instantaneous motion through movies or animations, and thus we perceive their motion as relatively slow. To address this issue, we propose a novel method of displaying exaggerated sword motions to allow a virtual reality user to enjoy a fast slash action. This method displays an arc-shaped motion blur effect along the predicted motion when the system detects the start of the slashing motion until the hand controller motion stops. Graphics of the sword are not displayed during this time. Therefore, the user is unaware of the actual trajectory of their input and how far it differs from the exaggerated motion blur effect.

    Rendering Glinty Granular Materials in Virtual Reality
    (The Eurographics Association, 2022) Kajs, Nynne; Gjøl, Mikkel; Gath, Jakob; Philippi, Henrik; Frisvad, Jeppe Revall; Bærentzen, Jakob Andreas; Theophilus Teo; Ryota Kondo
    Highly realistic rendering of grainy materials like sand is achievable given significant computational resources and a lot of time for the rendering of each frame. In an interactive virtual environment, we cannot afford such luxuries. Frame rates must be kept high and precomputation should be kept at a level that does not limit the interactivity. We propose a system for editable procedural generation of sand appearance and demonstrate interactive virtual reality (VR) inspection of the generated sand under different skies. Our method enables stable real-time rendering of the glinty appearance that granular materials exhibit as a function of observer distance. This enables simultaneous nearby and distant inspection of the material.
