José A. Canabal, Miguel A. Otaduy, Byungmoon Kim, Jose Echevarria We present a new system for interactive dendritic painting. Dendritic painting is characterized by the unique and intricate branching patterns that grow from the interaction of inks, solvents and medium. … Continue reading →

Local Bases for Model-Reduced Smoke Simulation Displacement-Correlated XFEM for Simulating Brittle Fracture Mixing Yarns and Triangles in Cloth Simulation Binary Ostensibly-Implicit Trees for Fast Collision Detection A Practical Method for Animating Anisotropic Elastoplastic Materials Fast and Scalable Solvers for the … Continue reading →

Olivier Mercier, Derek Nowrouzezahrai We present a flexible model reduction method for simulating incompressible fluids. We derive a novel vector field basis composed of localized basis flows that have simple analytic forms and can be tiled on regular lattices, avoiding … Continue reading →

Floyd M. Chitalu, Qinghai Miao, Kartic Subr, Taku Komura We present a remeshing-free brittle fracture simulation method under the assumption of quasi-static linear elastic fracture mechanics (LEFM). To achieve this, we devise two algorithms. First, we develop an approximate volumetric … Continue reading →

Juan J. Casafranca, Gabriel Cirio, Alejandro Rodríguez, Eder Miguel, Miguel A. Otaduy This paper presents a method to combine triangle and yarn models in cloth simulation, and hence leverage their best features. The majority of a garment uses a triangle-based … Continue reading →

Floyd M. Chitalu, Christophe Dubach, Taku Komura We present a simple, efficient and low-memory technique, targeting fast construction of bounding volume hierarchies (BVH) for broad-phase collision detection. To achieve this, we devise a novel representation of BVH trees in memory. … Continue reading →

Camille Schreck, Chris Wojtan This paper introduces a simple method for simulating highly anisotropic elastoplastic material behaviors like the dissolution of fibrous phenomena (splintering wood, shredding bales of hay) and materials composed of large numbers of irregularly-shaped bodies (piles of … Continue reading →

Ran Luo, Weiwei Xu, Tianjia Shao, Hongyi Xu, Yin Yang In deformable simulation, an important computing task is to calculate the gradient and derivative of the strain energy function in order to infer the corresponding internal force and tangent stiffness … Continue reading →

Tetsuya Takahashi, Ming C. Lin In physically-based simulation, it is essential to choose appropriate material parameters to generate desirable simulation results. In many cases, however, choosing appropriate material parameters is very challenging, and often tedious trial-and-error parameter tuning steps are … Continue reading →

We present a novel and general framework for the design and control of underwater soft-bodied animals. The whole body of an animal consisting of soft tissues is modeled by tetrahedral and triangular FEM meshes. The contraction of muscles embedded in … Continue reading →
