emg2face: Expressive Facial Animation with High-Density Surface EMG
Ganidhu Abey, Wendy Greening, Ashika Kamboj +5
Facial movements convey subtle and important information that is critical for human social communication. Optical methods for face capture are difficult or impossible to use when t…
A Splitting Architecture for Exact Reduced Coulomb Friction
Hongcheng Song, Ye Fan, Uri M. Ascher +1
Existing approaches to frictional contact dynamics typically either modify the Coulomb law to improve numerical robustness or solve the exact law in a fully coupled monolithic form…
Implicit frictional dynamics with soft constraints
Egor Larionov, Andreas Longva, Uri M. Ascher +2
Dynamics simulation with frictional contacts is important for a wide range of applications, from cloth simulation to object manipulation. Recent methods using smoothed lagged frict…
Volume Preserving Simulation of Soft Tissue with Skin
Seung Heon Sheen, Egor Larionov, Dinesh K. Pai
Simulation of human soft tissues in contact with their environment is essential in many fields, including visual effects and apparel design. Biological tissues are nearly incompres…
Simulating deformable objects for computer animation: a numerical perspective
Uri M. Ascher, Egor Larionov, Seung Heon Sheen +1
We examine a variety of numerical methods that arise when considering dynamical systems in the context of physics-based simulations of deformable objects. Such problems arise in va…
Geometric Numerical Integration of Inequality Constrained, Nonsmooth Hamiltonian Systems
Danny M. Kaufman, Dinesh K. Pai
We consider the geometric numerical integration of Hamiltonian systems subject to both equality and "hard" inequality constraints. As in the standard geometric integration setting,…
