Fast and Exact Continuous Collision Detection with Bernstein Sign Classification

Posted on August 28, 2014 by christopherbatty

Min Tang, Ruofeng Tong, Zhendong Wang, Dinesh Manocha We present fast algorithms to perform accurate CCD queries between triangulated models. Our formulation uses properties of the Bernstein basis and Bezier curves and reduces the problem to evaluating signs of polynomials. … Continue reading →

Coupling 3D Eulerian, Height Field and Particle Methods for the Simulation of Large Scale Liquid Phenomena

Posted on August 15, 2014 by christopherbatty

Nuttapong Chentanez, Matthias Mueller, Tae-Yong Kim We propose a new method to simulate large scale water phenomena by combining particle, 3D grid and height field methods. In contrast to most hybrid approaches that use particles to simulate foam and spray only, … Continue reading →

An Adaptive Virtual Node Algorithm with Robust Mesh Cutting

Posted on August 15, 2014 by christopherbatty

Yuting Wang, Chenfanfu Jiang, Craig Schroeder, Joseph Teran We present a novel virtual node algorithm (VNA) for changing tetrahedron mesh topology to represent arbitrary cutting triangulated surfaces. Our approach addresses a number of shortcomings in the original VNA of [MBF04]. First, we … Continue reading →

Optimization Integrator for Large Time Steps

Posted on August 2, 2014 by christopherbatty

Theodore F. Gast, Craig Schroeder 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 steps … Continue reading →

Sensitivity-optimized Rigging for Example-based Real-Time Clothing Synthesis

Posted on August 2, 2014 by christopherbatty

Weiwei Xu, Noboyuki Umetani, Qianwen Chao, Jie Mao, Xiaogang Jin, Xin Tong We present a real-time solution for generating detailed clothing deformations from pre-computed clothing shape examples. Given an input pose, it synthesizes a clothing deformation by blending skinned clothing deformations of nearby … Continue reading →
