Dan Koschier, Jan Bender, Barbara Solenthaler, Matthias Teschner Throughout the past decades, the graphics community has spent major resources on the research and development of physics simulators on the mission to computer-generate behaviors achieving outstanding visual effects or to make the virtual world indistinguishable from reality. The variety and impact of recent research based on […]

Qiang Chen, Tingsong Lu, Yang Tong, Guoliang Luo, Xiaogang Jin, Zhigang Deng As one of ubiquitous insects on the earth, butterflies are also widely-knownfor inspiring thrill resonance with their elegant and peculiar flights. However, realistically modeling and simulating butterfly flights, in particular, for real-time graphics and animation applications, remains an under-explored problem. In this paper […]

Teseo Schneider, Yixin Hu, Xifeng Gao, Jeremie Dumas, Denis Zorin, Daniele Panozzo The Finite Element Method (FEM) is widely used to solve discrete Partial Differential Equations (PDEs) in engineering and graphics applications. The popularity of FEM led to the development of a large family of variants, most of which require a tetrahedral or hexahedral mesh […]

Bolun Wang, Zachary Ferguson, Xin Jiang, Marco Attene, Daniele Panozzo, Teseo Schneider We introduce the first exact root parity counter for continuous collision detection (CCD). That is, our algorithm computes the parity (even or odd) of the number of roots of the cubic polynomial arising from a CCD query. We note that the parity is […]

Qisi Wang, Yutian Tao, Eric Brandt, Court Cutting, Eftychios Sifakis We present a method for the efficient processing of contact and collision in volumetric elastic models simulated using the Projective Dynamics paradigm. Our approach enables interactive simulation of tetrahedral meshes with more than half a million elements, provided that the model satisfies two fundamental properties: […]

Haozhe Su, Tao Xue, Chengguizi Han, Mridul Aanjaneya We present an arbitrary updated Lagrangian Material Point Method (A-ULMPM) to alleviate issues, such as the cell-crossing instability and numerical fracture, that plague state of the art Eulerian formulations of MPM, while still allowing for large deformations that arise in fluid simulations. Our proposed framework spans MPM […]
