Magnets in Motion

We introduce magnetic interaction for rigid body simulation. Our approach is based on an equivalent dipole method and as such it is discrete from the ground up. Our approach is symmetric as we base both field and force computations on … Continue reading

Algoryx and Phun, CMLabs

There seem to be quite a few companies in the business of physics simulation these days. Graham Fyffe pointed out this one to me: Algoryx focuses on 3D multi-physics simulations. They are also responsible for the Phun demo I posted … Continue reading

Thesis: Controlling Multibody Dynamics via Browsing and Time Reversal

Christopher Twigg’s thesis from CMU: “Animation techniques for controlling passive simulation are commonly based on an optimization paradigm: the user provides goals a priori, and sophisticated numerical methods minimize a cost function that represents these goals. Unfortunately, for multibody systems … Continue reading

Cosserat Nets

Cosserat nets are networks of elastic rods that are linked by elastic joints. They allow to represent a large variety of objects such as elastic rings, coarse nets, or truss structures. In this paper, we propose a novel approach to … Continue reading

PixeLux's DMM

I added Pixelux Entertainment’s link on the side.  They have developed a piece of software known as DMM (for  Digital Molecular Matter),  that “is a real-time finite element system that is being used in the “Force Unleashed”, an upcoming video … Continue reading

Book: Fluid simulation for computer graphics

“This book is designed to give the reader a practical introduction to fluid simulation for graphics. The field of fluid dynamics, even just in animation, is vast and so not every topic will be covered, and many wonderful papers will … Continue reading

Robust and Efficient Wave Simulations on Deforming Meshes

The goal of this paper is to enable the interactive simulation of phenomena such as animated fluid characters. While full 3D fluid solvers achieve this with control algorithms, these 3D simulations are usually too costly for real-time environments. In order … Continue reading

Fool Me Twice: Exploring and Exploiting Error Tolerance in Physics-Based Animation

The error tolerance of human perception offers a range of opportunities to trade numerical accuracy for performance in physics-based simulation. However, most previous approaches either focus exclusively on understanding the tolerance of the human visual system or burden the application … Continue reading

Feedback Control of Cumuliform Cloud Formation Based on Computational Fluid Dynamics

Clouds play an important role for creating realistic images of outdoor scenes. In order to generate realistic clouds, many methods have been developed for modeling and animating clouds. One of the most effective approaches for synthesizing realistic clouds is to … Continue reading

Polyhedral Finite Elements Using Harmonic Basis Functions

Finite element simulations in computer graphics are typically based on tetrahedral or hexahedral elements, which enables simple and efficient implementations, but in turn requires complicated remeshing in case of topological changes or adaptive refinement. We propose a flexible finite element … Continue reading
