Multi-species simulation of porous sand and water mixtures

A. Pradhana Tampubolon, T. Gast, G. Klar, C. Fu, J. Teran, C. Jiang, K. Museth We present a multi-species model for the simulation of gravity driven landslides and debris flows with porous sand and water interactions. We use continuum mixture theory to describe individual phases where each species individually obeys conservation of mass and momentum […]

Robust eXtended Finite Elements for Complex Cutting of Deformables

Dan Koschier, Jan Bender, Nils Thuerey In this paper we present a robust remeshing-free cutting algorithm on the basis of the eXtended Finite Element Method (XFEM) and fully implicit time integration. One of the most crucial points of the XFEM is that integrals over discontinuous polynomials have to be computed on subdomains of the polyhedral […]

Enriching Facial Blendshape Rigs with Physical Simulation

Yeara Kozlov, Derek Bradley, Moritz Bächer, Thabo Beeler, Markus Gross Oftentimes facial animation is created separately from overall body motion. Since convincing facial animation is challenging enough in itself, artists tend to create and edit the face motion in isolation. Or if the face animation is derived from motion capture, this is typically performed in […]

Example-Based Expressive Animation of 2D Rigid Bodies

Marek Dvorožňák, Pierre Bénard, Pascal Barla, Oliver Wang, Daniel Sýkora We present a novel approach to facilitate the creation of stylized 2D rigid body animations. Our approach can handle multiple rigid objects following complex physically-simulated trajectories with collisions, while retaining a unique artistic style directly specified by the user. Starting with an existing target animation […]

Real-time Interactive Tree Animation

We present a novel method for posing and animating botanical tree models interactively in real time. Unlike other state of the art methods which tend to produce trees that are overly flexible, bending and deforming as if they were underwater plants, our approach allows for arbitrarily high stiffness while still maintaining real-time frame rates without […]

Physically Based Video Editing

Bazin, Jean-Charles; Plüss (Kuster), Claudia; Yu, Guo; Martin, Tobias; Jacobson, Alec; Gross, Markus Convincing manipulation of objects in live action videos is a difficult and often tedious task. Skilled video editors achieve this with the help of modern professional tools, but complex motions might still lack physical realism since existing tools do not consider the […]

Efficient and Reliable Self-Collision Culling using Unprojected Normal Cones

Tongtong Wang, Zhihua Liu, Min Tang, Roufeng Tong, and Dinesh Manocha We present an efficient and accurate algorithm for self-collision detection in deformable models. Our approach can perform discrete and continuous collision queries on triangulated meshes. We present a simple and linear time algorithm to perform the normal cone test using the unprojected 3D vertices, […]

Interactive Modeling and Authoring of Climbing Plants

Torsten Hädrich, Bedrich Benes, Oliver Deussen, Sören Pirk We present a novel system for the interactive modeling of developmental climbing plants with an emphasis on efficient control and plausible physics response. A plant is represented by a set of connected anisotropic particles that respond to the surrounding environment and to their inner state. Each particle […]

Art-Directed Muscle Simulation for High-End Facial Animation

Matthew Cong, Kiran S. Bhat, Ronald Fedkiw We propose a new framework for the simulation of facial muscle and flesh that so significantly improves the technique that it allows for immediate mainstream use of anatomically and biomechanically accurate muscle models as a bread and butter technique in a high-end production quality pipeline. The key idea […]

Two-way coupling of fluids to reduced deformable bodies

Wenlong Lu, Ning Jin, Ronald Fedkiw We propose a fully monolithic two-way coupling framework that couples incompressible fluids to reduced deformable bodies. Notably, the resulting linear system matrix is both symmetric and positive-definite. Our method allows for the simulation of interesting free-surface as well as underwater phenomena, enabling the use of reduced deformable bodies as […]
