    Splash in a Flash: Sharpness-aware Minimization for Efficient Liquid Splash Simulation
    (The Eurographics Association, 2022) Jetly, Vishrut; Ibayashi, Hikaru; Nakano, Aiichiro; Sauvage, Basile; Hasic-Telalovic, Jasminka
    We present sharpness-aware minimization (SAM) for fluid dynamics which can efficiently learn the plausible dynamics of liquid splashes. Due to its ability to achieve robust and generalizing solutions, SAM efficiently converges to a parameter set that predicts plausible dynamics of elusive liquid splashes. Our training scheme requires 6 times smaller number of epochs to converge and, 4 times shorter wall-clock time. Our result shows that sharpness of loss function has a close connection to the plausibility of fluid dynamics and suggests further applicability of SAM to machine learning based fluid simulation.

    Stroke based Painterly Inbetweening
    (The Eurographics Association, 2022) Barroso, Nicolas; Fondevilla, Amélie; Vanderhaeghe, David; Sauvage, Basile; Hasic-Telalovic, Jasminka
    Creating a 2D animation with visible strokes is a tedious and time consuming task for an artist. Computer aided animation usually focus on cartoon stylized rendering, or is built from an automatic process as 3D animations stylization, loosing the painterly look and feel of hand made animation. We propose to simplify the creation of stroke-based animations: from a set of key frames, our methods automatically generates intermediate frames to depict the animation. Each intermediate frame looks as it could have been drawn by an artist, using the same high level stroke based representation as key frame, and in succession they display the subtle temporal incoherence usually found in hand-made animations.
