Ante Qu, Doug L James It is increasingly common to model, simulate, and process complex materials based on loopy structures, such as in yarn-level cloth garments, which possess topological constraints between inter-looping curves. While the input model may satisfy specific … Continue reading →

Zachary Ferguson, Minchen Li, Teseo Schneider, Francisca Gil-Ureta, Timothy Langlois, Chenfanfu Jiang, Denis Zorin, Danny M. Kaufman, Daniele Panozzo We introduce the first implicit time-stepping algorithm for rigid body dynamics, with contact and friction, that guarantees intersection-free configurations at every … Continue reading →

Victor Romero, Mickael Ly, Abdullah Haroon Rasheed, Raphael Charrondiere, Arnaud Lazarus, Sebastian Neukirch, Florence Bertails-Descoubes We introduce a selected set of protocols inspired from the Soft Matter Physics community in order to validate Computer Graphics simulators of slender elastic structures … Continue reading →

Sai Praveen Bangaru, Jesse Michel, Kevin Mu, Gilbert Bernstein, Tzu-Mao Li, Jonathan Ragan-Kelley Emerging research in computer graphics, inverse problems, and machine learning requires us to differentiate and optimize parametric discontinuities. These discontinuities appear in object boundaries, occlusion, contact, and … Continue reading →

T. Hädrich, D. T. Banuti, W. Pałubicki, S. Pirk, D. L. Michels. Resulting from changing climatic conditions, wildfires have become an existential threat across various countries around the world. The complex dynamics paired with their often rapid progression renders wildfires … Continue reading →

Haozhe Su*, Tao Xue*, Chengguizi Han, Chenfanfu Jiang, Mridul Aanjaneya (*Joint first authors) We assume that the viscous forces in any liquid are simultaneously local and non-local, and introduce the extended POM-POM model [Mcleish and Larson 1998; Oishi et al. … Continue reading →

Yuanming Hu, Jiafeng Liu, Xuanda Yang, Mingkuan Xu, Ye Kuang, Weiwei Xu, Qiang Dai, William T. Freeman, Fredo Durand High-resolution simulations can deliver great visual quality, but they are often limited by available memory, especially on GPUs. We present a … Continue reading →

Egor Larionov, Ye Fan, Dinesh K. Pai Frictional contact between deformable elastic objects remains a difficult simulation problem in computer graphics. Traditionally, contact has been resolved using sophisticated collision detection schemes and methods that build on the assumption that contact … Continue reading →

Ryoichi Ando, Christopher Batty We propose a new adaptive liquid simulation framework that achieves highly detailed behavior with reduced implementation complexity. Prior work has shown that spatially adaptive grids are efficient for simulating large-scale liquid scenarios, but in order to … Continue reading →

Gilles Daviet Frictional contacts are the primary way by which physical bodies interact, yet they pose many numerical challenges. Previous works have devised robust methods for handling collisions in elastic bodies, cloth, or fiber assemblies such as hair, but the … Continue reading →
