Synthesizing Waves from Animated Height Fields

Michael B. Nielsen, Andreas Soderstrom, Robert Bridson Computer animated ocean waves for feature films are typically carefully choreographed to match the vision of the director and to support the telling of the story. The rough shape of these waves is established in the previsualization (previs) stage, where artists use a variety of modeling tools with fast feedback to […]

Interactive High-Resolution Boundary Surfaces for Deformable Bodies with Changing Topology

Jun Wu, Christian Dick, Rudiger Westermann Recent work has demonstrated that composite finite-elements provide an effective means for physically based modeling of deformable bodies. In this paper we present a number of highly effective improvements of previous work to allow for a high-performance and high-quality simulation of boundary surfaces of deformable bodies with changing topology, […]

SIGGRAPH Course: Data-Driven Simulation Methods in Computer Graphics: Cloth, Tissue, and Faces

Miguel Otaduy, Bernd Bickel, Derek Bradley, Huamin Wang In recent years, the field of computer animation has witnessed the invention of multiple simulation methods that exploit pre-recorded data to improve the performance and/or realism of dynamic deformations. Various methods have been presented concurrently, and they present differences, but also similarities, that have not yet been […]

SIGGRAPH Course: FEM Simulation of 3D Deformable Solids: A practitioner's guide to theory, discretization and model reduction

Eftychios Sifakis and Jernej Barbic A practical guide to finite-element-method (FEM) simulation of 3D deformable solids reviews essential offline FEM simulation techniques: complex nonlinear materials, invertible treatment of elasticity, and model-reduction techniques for real-time simulation. Simulations of deformable solids are important in many applications in computer graphics, including film special effects, computer games, and virtual […]

Controlling Liquids Using Meshes

Karthik Raveendran, Nils Thuerey, Chris Wojtan, Greg Turk We present an approach for artist-directed animation of liquids using multiple levels of control over the simulation, ranging from the overall tracking of desired shapes to highly detailed secondary effects such as dripping streams, separating sheets of fluid, surface waves and ripples. The first portion of our […]

Smoke Sheets for Graph-Structured Vortex Filaments

Alfred Barnat, Nancy S. Pollard Smoke is one of the core phenomena which fluid simulation techniques in computer graphics have attempted to capture. It is both well understood mathematically and important in lending realism to computer generated effects. In an attempt to overcome the diffusion inherent to Eulerian grid-based simulators, a technique has recently been […]
