Tuur Stuyck, Fang Da, Sunil Hadap, Philip Dutré This paper presents a realistic digital oil painting system, specifically targeted at the real-time performance on highly resource constrained portable hardware such as tablets and iPads. To effectively use the limited computing … Continue reading →

Pierre-Luc Manteaux, Ulysse Vimont, Chris Wojtan, Damien Rohmer, Marie-Paule Cani We propose an interactive sculpting system for seamlessly editing pre-computed animations of liquid, without the need for any re-simulation. The input is a sequence of meshes without correspondences representing the … Continue reading →

Marcel Weiler, Dan Koschier, Jan Bender We present a new method for particle based fluid simulation, using a combination of Projective Dynamics and Smoothed Particle Hydrodynamics (SPH). The Projective Dynamics framework allows the fast simulation of a wide range of … Continue reading →

Matthias Müller, Nuttapong Chentanez, Miles Macklin In computer graphics, simulated objects typically have two or three different representations, a visual mesh, a simulation mesh and a collection of convex shapes for collision handling. Using multiple representations requires skilled authoring and … Continue reading →

Miles Macklin, Matthias Muller, Nuttapong Chentanez We address the long-standing problem of iteration count and time step dependent constraint stiffness in position-based dynamics (PBD). We introduce a simple extension to PBD that allows it to accurately and efficiently simulate arbitrary … Continue reading →

Matthias Muller, Jan Bender, Nuttapong Chentanez, Miles Macklin We present a novel algorithm to extract the rotational part of an arbitrary 3×3 matrix. This problem lies at the core of two popular simulation methods in computer graphics, the co-rotational Finite … Continue reading →

Nathan Mitchell, Michael Doescher, Eftychios Sifakis We introduce a new numerical approach for the solution of grid-based discretizations of nonlinear elastic models. Our method targets the linearized system of equations within each iteration of the Newton method, and combines elements … Continue reading →

Rene Winchenbach, Hendrik Hochstetter, Andreas Kolb In this paper we present a new approach to create neighbor lists with strict memory bounds for incompressible Smoothed Particle Hydrodynamics (SPH) simulations. Our proposed approach is based on a novel efficient predictive-corrective algorithm … Continue reading →

Florian Canezin, Gael Guennebaud, Loïc Barthe Particle based simulations are widely used in computer graphics. In this field, several recent results have improved the simulation itself or improved the tension of the final fluid surface. In current particle based implementations, the particle … Continue reading →
