Particle-based Liquid Control using Animation Templates

Posted on October 5, 2020 by christopherbatty

Arnaud Schoentgen, Pierre Poulin, Emmanuelle Darles, Philippe Meseure It is notoriously difficult for artists to control liquids while generating plausible animations. We introduce a new liquid control tool that allows users to load, transform, and apply precomputed liquid simulation templates … Continue reading →

An Extended Cut-cell method for Sub-Grid Liquids Tracking with Surface Tension

Posted on October 3, 2020 by christopherbatty

Yi-Lu Chen, Jonathan Meier, Barbara Solenthaler, Vinicius C. Azevedo Simulating liquid phenomena utilizing Eulerian frameworks is challenging, since highly energetic flows often induce severe topological changes, creating thin and complex liquid surfaces. Thus, capturing structures that are small relative to … Continue reading →

Higher-Order Time Integration for Deformable Solids

Posted on October 3, 2020 by christopherbatty

Fabian Löschner, Andreas Longva, Stefan Jeske, Tassilo Kugelstadt, Jan Bender Visually appealing and vivid simulations of deformable solids represent an important aspect of physically based computer animation. For the temporal discretization, it is customary in computer animation to use first-order … Continue reading →

Detailed Rigid Body Simulation with Extended Position Based Dynamics

Posted on October 3, 2020 by christopherbatty

Matthias Müller, Miles Macklin, Nuttapong Chentanez, Stefan Jeschke, Tae-Yong Kim We present a rigid body simulation method that can resolve small temporal and spatial details by using a quasi explicit integration scheme that is unconditionally stable. Traditional rigid body simulators … Continue reading →

Primal/Dual Descent Methods for Dynamics

Posted on October 3, 2020 by christopherbatty

Miles Macklin, Kenny Erleben, Matthias Müller-Fischer, Nuttapong Chentanez, Stefan Jeschke, Tae-Yong Kim We examine the relationship between primal, or force-based, and dual, or constraint-based formulations of dynamics. Variational frameworks such as Projective Dynamics have proved popular for deformable simulation, however … Continue reading →

Making Procedural Water Waves Boundary-aware

Posted on October 3, 2020 by christopherbatty

Stefan Jeschke, Christian Hafner, Nuttapong Chentanez, Miles Macklin, Matthias Muller-Fischer, Chris Wojtan The “procedural” approach to animating ocean waves is the dominant algorithm for animating larger bodies of water in interactive applications as well as in off-line productions — it … Continue reading →

Latent Space Subdivision: Stable and Controllable Time Predictions for Fluid Flow

Posted on October 3, 2020 by christopherbatty

Steffen Weiwel, Byungsoo Kim, Vinicius C. Azevedo, Barbara Solenthaler, Nils Thuerey We propose an end-to-end trained neural network architecture to robustly predict the complex dynamics of fluid flows with high temporal stability. We focus on single-phase smoke simulations in 2D … Continue reading →
