Cosserat Rod with rh-Adaptive Discretization
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Rod-like one-dimensional elastic objects often exhibit complex behaviors which pose great challenges to the discretization method for pursuing a faithful simulation. By only moving a small portion of material points, the ...
Semi-analytical Solid Boundary Conditions for Free Surface Flows
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
The treatment of solid boundary conditions remains one of the most challenging parts in the SPH method. We present a semianalytical approach to handle complex solid boundaries of arbitrary shape. Instead of calculating a ...
Simulation of Arbitrarily-shaped Magnetic Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Abstract We propose a novel method for simulating rigid magnets in a stable way. It is based on analytic solutions of the magnetic vector potential and flux density, which make the magnetic forces and torques calculated ...
Fracture Patterns Design for Anisotropic Models with the Material Point Method
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Physically plausible fracture animation is a challenging topic in computer graphics. Most of the existing approaches focus on the fracture of isotropic materials. We proposed a frame-field method for the design of anisotropic ...
A Novel Plastic Phase-Field Method for Ductile Fracture with GPU Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
efficiently simulate ductile fracture with GPU optimization. At the theoretical level of physically-based modeling and simulation, our PPF approach assumes the fracture sensitivity of the material increases with the plastic ...
Adjustable Constrained Soft-Tissue Dynamics
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Physically based simulation is often combined with geometric mesh animation to add realistic soft-body dynamics to virtual characters. This is commonly done using constraint-based simulation whereby a soft-tissue simulation ...
