A New Implicit Integration Method for Low Damped Cloth Simulation
نویسندگان
چکیده
This paper discusses a new technique that reproduces a stable cloth without introducing excessive damping artifacts. Semi-implicit integration methods have been widely used in cloth simulations for their high stability and speed. Artificial internal damping forces are derived from the linearization process of semi-implicit integration. This makes the system highly stable. However, the artificial internal damping forces are generated with respect to not only internal deformations but also rotational rigid motions. This damping artifact significantly degrades the realism of the cloth simulation. Hence, we propose a new implicit integration method to decrease this artifact. The artificial internal damping forces are computed by considering the pure internal deformations alone, and are stably incorporated into the dynamical system. As a result, our simulator could reproduce a wide range of cloth materials without the excessive damping artifacts in realtime.

Asynchronous Cloth Simulation
This paper presents a new method for cloth simulation, which uses asynchronous variants of both time integration and collision handling. Implicit integration methods like backward Euler and BDF-2 are very popular in computer graphics, since they allow for fast and stable animations. However, when combined with large time steps, their inherent numerical dissipation results in over-damped simulat...

Implicit integration methods have contributed to large performance enhancements in the field of simulation of particle-system mechanical models. While Backward Euler and BDF-2 methods are now widely used for cloth simulation applications, the Implicit Midpoint method is often overlooked, because of its poor stability properties. It is however as simple to implement as Backward Euler, and offers...
متن کاملEfficiency of Anti-Hourglassing Approaches in Finite Element Method (TECHNICAL NOTE)
one of the simplest numerical integration method which provides a large saving in computational efforts, is the well known one-point Gauss quadrature which is widely used for 4 nodes quadrilateral elements. On the other hand, the biggest disadvantage to one-point integration is the need to control the zero energy modes, called hourglassing modes, which arise. The efficiency of four different an...
