Bo Ren, Jiahui Huang, Ming C. Lin, Shi-Min Hu Real world dendritic growths show charming structures by their exquisite balance between the symmetry and randomness in the crystal formation. Other than the variety in the natural crystals, richer visual appearance … Continue reading →

Minjae Lee, David Hyde, Michael Bao, Ronald Fedkiw We propose a novel framework for hair animation as well as hair-water interaction that supports millions of hairs. First, we develop a hair animation framework that embeds hair into a tetrahedralized volume … Continue reading →

Yu Ju Chen, Uri M. Ascher, Dinesh K. Pai High quality simulations of the dynamics of soft flexible objects can be rather costly, because the assembly of internal forces through an often nonlinear stiffness at each time step is expensive. … Continue reading →

X. L. Wang, M. Tang, D. Manocha, Ruo-Feng Tong Bounding volume hierarchy (BVH) has been widely adopted as the acceleration structure in broad-phase collision detection. Previous state-of-the-art BVH-based collision detection approaches exploited the spatio-temporal coherence of simulations by maintaining a … Continue reading →

Dimitar Dinev, Tiantian Liu, Ladislav Kavan We present a new time integration method featuring excellent stability and energy conservation properties, making it particularly suitable for real-time physics. The commonly used backward Euler method is stable but introduces artificial damping. Methods … Continue reading →

Kui Wu, Nghia Truong, Cem Yuksel, Rama Hoetzlein We introduce efficient, large scale fluid simulation on GPU hardware using the fluid-implicit particle (FLIP) method over a sparse hierarchy of grids represented in NVIDIA GVDB Voxels. Our approach handles tens of … Continue reading →

Direct Position-Based Solver for Stiff Rods A Physically Consistent Implicit Viscosity Solver for SPH Fluids Fast Fluid Simulations with Sparse Volumes on the GPU Efficient BVH-based Collision Detection with Ordering and Restructuring Hair Modeling and Simulation by Style Extended Narrow … Continue reading →

Crispin Deul, Tassilo Kugelstadt, Marcel Weiler, Jan Bender In this paper, we present a novel direct solver for the efficient simulation of stiff, inextensible elastic rods within the Position-Based Dynamics (PBD) framework. It is based on the XPBD algorithm, which … Continue reading →

Marcel Weiler, Dan Koschier, Magnus Brand, Jan Bender In this paper, we present a novel physically consistent implicit solver for the simulation of highly viscous fluids using the Smoothed Particle Hydrodynamics (SPH) formalism. Our method is the result of a … Continue reading →

Breannan Smith, Fernando de Goes, Theodore Kim Non-linear hyperelastic energies play a key role in capturing the fleshy appearance of virtual characters. Real-world, volume-preserving biological tissues have Poisson’s ratios near 1/2, but numerical simulation within this regime is notoriously challenging. … Continue reading →
