    A Choreographic Authoring System for Character Dance Animation Reflecting a User's Preference
    (The Eurographics Association, 2016) Kakitsuka, Ryo; Tsukuda, Kosetsu; Fukayama, Satoru; Iwamoto, Naoya; Goto, Masataka; Morishima, Shigeo; Jan Bender
    We propose a new system for constructing character dance animation by considering animator's preferences. First, a user of the proposed system assigns a preferred motion, obtained through a searching algorithm, to arbitrary part in the music. Then the proposed system automatically assigns motions to the other remaining parts of the music by using motions in a database. By this system, we can create a new dance performance for character animation considering a user's preference.

    Friction Sound Synthesis of Deformable Objects based on Adhesion Theory
    (The Eurographics Association, 2016) Nakatsuka, Takayuki; Morishima, Shigeo; Jan Bender
    Friction sound is one of the closest sounds for us in any situations. Most of those sounds are created by Foley artists in computer animations. However, synthesizing sounds in all scenes need technical skills and take high costs. In this research, we propose a novel physically-based approach to synthesize various kinds of friction sounds based on dynamics simulation.

    Online Compression of Rigid Body Simulations using Physics-Inspired Interpolation
    (ACM, 2017) Jeruzalski, Timothy; Fiume, Eugene; Jacobson, Alec; Levin, David I.W.; Bernhard Thomaszewski and KangKang Yin and Rahul Narain
    Methods to compress simulation data are invaluable as they facilitate efficient transmission along the visual effects pipeline, fast and efficient replay of simulations for visualization and enable storage of scientific data. However, all current approaches to compressing simulation data require access to the entire dynamic simulation, leading to large memory requirements and additional computational burden. In this paper we perform physics-based simulation compression in an online fashion, requiring access to only a narrow window of simulation data at a time and achieving good agreement with the original simulation.

    Sketch-Based Per-Frame Inverse Kinematics
    (The Eurographics Association, 2016) Mahmudi, Mentar; Harish, Pawan; Callennec, Benoît Le; Boulic, Ronan; Jan Bender
    We present a method that uses a sketch-based interface in conjunction with a parallelized per-frame inverse kinematics (Parallel- PFIK) method for the purpose of motion editing. The artist creates and edits 3D constraints through an intuitive and easy to use 2D interface. These constraints are passed to Parallel-PFIK in order to solve for the joint angles of the character in a fast and efficient manner. Parallel-PFIK employs multicore processors and current generation GPUs extending parallel damped least squares inverse kinematics to multiple frames in order to solve the entire animation in real time. Our method allows users to create and edit 3D animations using an intuitive 2D sketch-based interface bringing 2D artist into 3D character animation.

    The Stretch-Engine: A Method for Adjusting the Exaggeration of Bipedal Characters Through Squash and Stretch
    (ACM, 2017) Ibrahim, Zaid H.; Bernhard Thomaszewski and KangKang Yin and Rahul Narain
    This paper describes a new method to control changes in a character's form during exaggeration, through squash and stretch (SS). The Stretch-Engine is the result of this method, designed to be integrated into an existing animation system, Maya. The Stretch- Engine is a three-part system where the first is a bipedal-humanoid rig with controls necessary for animation and the ability to SS its limbs. The second is a set of rules determined from studying Looney Tunes animation to create a range of SS. The third is a user interface that allows users to control changes in SS using 3D curves created within the Maya interface.

    ZooBuilder: 2D and 3D Pose Estimation for Quadrupeds Using Synthetic Data
    (The Eurographics Association, 2020) Fangbemi, Abassin Sourou; Lu, Yi Fei; Xu, Maoyuan; Luo, Xiaowu; Rolland, Alexis; Raissi, Chedy; Holden, Daniel
    This work introduces a novel strategy for generating synthetic training data for 2D and 3D pose estimation of animals using keyframe animations. With the objective to automate the process of creating animations for wildlife, we train several 2D and 3D pose estimation models with synthetic data, and put in place an end-to-end pipeline called ZooBuilder. The pipeline takes as input a video of an animal in the wild, and generates the corresponding 2D and 3D coordinates for each joint of the animal's skeleton. With this approach, we produce motion capture data that can be used to create animations for wildlife.
