Misconceptions of PD Control in Animation
(The Eurographics Association, 2012)
In this paper, we address certain misconceptions that have been perpetuated in the animation practice and research for quite some time related to the proportional-derivative (PD) control of physics-based systems. Because ...
Linear-Time Smoke Animation with Vortex Sheet Meshes
(The Eurographics Association, 2012)
We present the first quality physics-based smoke animation method which runs in time approximately linear in the size of the rendered two-dimensional visual detail. Our fundamental representation is a closed triangle mesh ...
Efficient Unsupervised Temporal Segmentation of Human Motion
(The Eurographics Association, 2014)
This work introduces an efficient method for fully automatic temporal segmentation of human motion sequences and similar time series. The method relies on a neighborhood graph to partition a given data sequence into distinct ...
Adaptive Tetrahedral Meshes for Brittle Fracture Simulation
(The Eurographics Association, 2014)
We present a method for the adaptive simulation of brittle fracture of solid objects based on a novel reversible tetrahedral mesh refinement scheme. The refinement scheme preserves the quality of the input mesh to a large ...
Optimization Integrator for Large Time Steps
(The Eurographics Association, 2014)
Practical time steps in today's state-of-the-art simulators typically rely on Newton's method to solve large systems of nonlinear equations. In practice, this works well for small time steps but is unreliable at large time ...
Strain Based Dynamics
(The Eurographics Association, 2014)
We propose a new set of constraints within the Position Based Dynamics (PBD) framework that allow the control of strain in directions that are independent of the edge directions of the simulation mesh. Instead of constraining ...
A Peridynamic Perspective on Spring-Mass Fracture
(The Eurographics Association, 2014)
The application of spring-mass systems to the animation of brittle fracture is revisited. The motivation arises from the recent popularity of peridynamics in the computational physics community. Peridynamic systems can be ...
Large-Scale Finite State Game Engines
(The Eurographics Association, 2016)
This paper presents a new model reduction technique that exploits large-scale, parallel precomputation to create interactive, real-time games with the visual fidelity of offline rendered films.We present an algorithm to ...
Versatile Interactions at Interfaces for SPH-Based Simulations
(The Eurographics Association, 2016)
The realistic capture of various interactions at interfaces is a challenging problem for SPH-based simulation. Previous works have mainly considered a single type of interaction, while real-world phenomena typically exhibit ...
Art-Directed Muscle Simulation for High-End Facial Animation
(The Eurographics Association, 2016)
We propose a new framework for the simulation of facial muscle and flesh that so significantly improves the technique that it allows for immediate mainstream use of anatomically and biomechanically accurate muscle models ...
