    Interactive Visualization of Historical Fabrics at Yarn Level using Sphere Tracing
    (The Eurographics Association, 2022) Pérez-Aixendri, Manolo; Gimeno, Jesús; Portalés, Cristina; Casanova-Salas, Pablo; Posada, Jorge; Serrano, Ana
    In this paper we present preliminary results of a new approach for interactive visualization of historical fabrics at yarn level based on models using Signed Distance Functions. They are compared with the results of Virtual Loom, an interactive application for rendering historical fabrics from the 15th to the 19th century, resulting from the European SilkNow project [PSA*18]. Yarns used on these fabrics has an special complexity due to a metallic cover that appears in some elements of the fabric. This new approach is based on rendering using Sphere Tracing. We will propose a signed distance function that allows both the visualization of a single yarn and a complete fabric in real time.

    NeodiagVR: Virtual Reality Apgar test environment
    (The Eurographics Association, 2022) Ferry, Lucas; Gimeno, Jesús; Estañ, Francisco Javier; Núñez, Francisco; Balaguer, Evelin; Fernández, Marcos; Portalés, Cristina; Posada, Jorge; Serrano, Ana
    Owing to the lack of accessibility of postpartum rooms nowadays, which are needed to teach the correct assessment of newborn health status to medical students, virtual reality and simulation are increasingly used for teaching and assessing visual perception tests that evaluate the condition of the newborn. This paper aims to explain the operation of the Apgar test evaluation simulator in a virtual reality environment. This virtual environment can be manipulated externally from a web browser to visualize and control the course of the simulation in real-time. In addition, an offline version would allow initialization and visualization of the Apgar test parameters without the need for synchronization with the virtual environment.
