EigenFit for Consistent Elastodynamic Simulation Across Mesh Resolution
Elastodynamic system simulation is a key procedure in computer graphics and robotics applications. To enable these simulations, the governing differential system is discretized in space (employing FEM) and then in time. ...
Subspace Neural Physics: Fast Data-Driven Interactive Simulation
Data-driven methods for physical simulation are an attractive option for interactive applications due to their ability to trade precomputation and memory footprint in exchange for improved runtime performance. Yet, existing ...
A Robust Volume Conserving Method for Character-Water Interaction
We propose a novel volume conserving framework for character- water interaction, using a novel volume-of-fluid solver on a skinned tetrahedral mesh, enabling the high degree of the spatial adaptiv- ity in order to capture ...

Human Articular Movement Algorithm to Simulate Muscle Contraction and Embedded Tissue Deformation
The visualization of human articular movements associated with internal deformation is critical for many fields including biome- chanics. In this work, we present a novel algorithm to describe realistic articular movement ...
Interaction Motion Retargeting to Highly Dissimilar Furniture Environment
Retageting a human-environment interaction motion to a different environment remains as an important research topic in computer animation. This paper introduces a novel method that can retarget an interaction motion to ...
GPU-Based Contact-Aware Trajectory Optimization Using A Smooth Force Model
We present a new formulation of trajectory optimization for articulated bodies. Our approach uses a fully differentiable dynamic model of the articulated body, and a smooth force model that approximates all kinds of ...
Online Motion Synthesis Framework using a Simple Mass Model based on Predictive Coding
Hybrid-based character animation utilizing the motion capture data and a simplified physics model allows synthesizing the motion data without losing its naturalness of the original motion. However, using both the physical ...
Fast Simulation of Deformable Characters with Articulated Skeletons in Projective Dynamics
We propose a fast and robust solver to simulate continuum-based deformable models with constraints, in particular, rigid-body and joint constraints useful for soft articulated characters. Our method embeds degrees of freedom ...
Divergence-Free and Boundary-Respecting Velocity Interpolation Using Stream Functions
In grid-based fluid simulation, discrete incompressibility of each cell is enforced by the pressure projection. However, pointwise velocities constructed by interpolating the discrete velocity samples from the staggered ...
