Ryan Goldade, Mridul Aanjaneya, Christopher Batty We propose to enhance the capability of standard free-surface flow simulators with efficient support for immersed bubbles through two new models: constraint-based bubbles and affine fluid regions. Unlike its predecessors, our constraint-based model entirely … Continue reading →

Lei Lan, Ran Luo, Marco Fratarcangeli, Weiwei Xu, Huamin Wang, Xiaohu Guo, Junfeng Yao, Yin Yang We propose a framework for the interactive simulation of nonlinear de-formable objects. The primary feature of our system is the seamless integration of deformable … Continue reading →

Rosa M. Sánchez-Banderas, Alejandro Rodríguez, Héctor Barreiro, Miguel A. Otaduy This paper introduces a method to simulate complex rod assemblies and stacked layers with implicit contact handling, through Eulerian-on-Lagrangian (EoL) discretizations. Previous EoL methods fail to handle such complex situations, … Continue reading →

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 →
