    Integrating Local Collision Avoidance with Shortest Path Maps
    (The Eurographics Association, 2020) Sharma, Ritesh; Farias, Renato; Kallmann, Marcelo; Ritschel, Tobias and Eilertsen, Gabriel
    The effective integration of local collision avoidance with global path planning becomes a necessity when multi-agent systems need to be simulated in complex cluttered environments. This work presents our first results exploring the new approach of integrating Shortest Path Maps (SPMs) with local collision avoidance in order to provide optimal paths for agents to navigate around obstacles toward their goal locations. Our GPU-based SPM implementation is available.

    Interactive Assembly and Animation of 3D Digital Garments
    (The Eurographics Association, 2020) Nylén, Oskar; Pall, Pontus; Ishiwaka, Yuko; Suda, Kazuto; Fratarcangeli, Marco; Wilkie, Alexander and Banterle, Francesco
    We present a novel real-time tool for sewing together 2D patterns, enabling quick assembly of visually plausible, interactively animated garments for virtual characters. The process is assisted by ad-hoc visual hints and allows designers to import 2D patterns from any CAD-tool, connect them using seams around a 3D character with any body type, and assess the overall quality during the character animation. The cloth is numerically simulated including robust modeling of contact of the cloth with itself and with the character's body. Overall, our tool allows for fast prototyping of virtual garments, achieving immediate feedback on their behaviour and visual quality on an animated character, in effect speeding up the content production pipeline for visual effects applications involving clothed characters.
