The program for VRIPHYS 2011 is up, which includes the following physics-related papers: Simulating inextensible cloth using locking-free triangle meshes Adding physics to animated characters using oriented particles Focused ultrasound – Efficient GPU simulation methods for therapy planning Time adaptive … Continue reading →

Matthias Muller, Nuttapong Chentanez We present a method to enhance the realism of animated characters by adding physically based secondary motion to deformable parts such as cloth, skin or hair. To this end, we extend the oriented particles approach to incorporate … Continue reading →

Bo Zhu, Michiaki Iwata, Ryo Haraguchi, Takashi Ashahara, Nobukuyuki Umetani, Takeo Igarashi, Kazuo Nakazawa This paper presents a lightweight sketching system that enables interactive illustration of complex fluid systems. Users can sketch on a 2.5-dimensional (2.5D) canvas to design the … Continue reading →

Zhi Yuan, Fan Chen, Ye Zhao Fluid animation practitioners face great challenges from the complexity of flow dynamics and the high cost of numerical simulation. A major hindrance is the uncertainty of fluid behavior after simulation resolution increases and extra … Continue reading →

Min Tang, Dinesh Manocha, Sung-Eui Yoon, Peng Du, Jae-Pil Heo, Ruofeng Tong We present a novel culling algorithm to perform fast and robust continuous collision detection between deforming volume meshes. This includes a continuous separating axis test that can conservatively … Continue reading →

Karthik Raveendran, Chris Wojtan, Greg Turk We present a new algorithm for enforcing incompressibility for Smoothed Particle Hydrodynamics (SPH) by preserving uniform density across the domain. We propose a hybrid method that uses a Poisson solve on a coarse grid … Continue reading →

Nuttapong Chentanez, Matthias Mueller We present a multigrid method for solving the linear complementarity problem (LCP) resulting from discretizing the Poisson equation subject to separating solid boundary conditions in an Eulerian liquid simulation’s pressure projection step. The method requires only … Continue reading →

David Harmon, Qingnan Zhou, Denis Zorin Asynchronous variational integration of layered contact models provides a framework for robust collision handling, correct physical behavior, and guaranteed eventual resolution of even the most difficult contact problems. Yet, even for low-contact scenarios, this … Continue reading →

The subset of physics-based animation papers includes: Pattern-Guided Smoke Animation with Lagrangian Coherent Structure A Hybrid Iterative Solver for Robustly Capturing Coulomb Friction in Hair Dynamics Sketch-Based Dynamic Illustration of Fluid Systems

Ruogang Huang, Zeki Melek, John Keyser In this work, we describe an automated method for directing the control of a high resolution gaseous fluid simulation based on the results of a lower resolution preview simulation. Small variations in accuracy between … Continue reading →
