Long Range Constraints for Rigid Body Simulations
(ACM, 2017)
The two main constraints used in rigid body simulations are contacts and joints. Both constrain the motion of a small number of bodies in close proximity. However, it is often the case that a series of constraints restrict ...
Small Steps in Physics Simulation
(ACM, 2019)
In this paper we re-examine the idea that implicit integrators with large time steps offer the best stability/performance trade-off for stiff systems. We make the surprising observation that performing a single 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 ...
Real-time Simulation of Large Elasto-Plastic Deformation with Shape Matching
(The Eurographics Association, 2016)
Shape matching is a popular method for simulating deformable objects in real time as it is fast and stable at large time steps. Although shape matching can simulate large elastic deformation and ductile fracturing, until ...
