Abstract
We present a novel meshfree technique for animating
free surface viscous liquids with jet buckling effects, such as
coiling and folding. Our technique is based on Smoothed Particle
Hydrodynamics (SPH) fluids and allows more realistic and
complex viscous behaviors than the preceding SPH frameworks
in computer animation literature. The viscous liquid is modeled
by a non-Newtonian fluid flow and the variable viscosity under
shear stress is achieved using a viscosity model known as Cross
model. The proposed technique is efficient and stable, and our
framework can animate scenarios with high resolution of SPH
particles in which the simulation speed is significantly accelerated
by using Computer Unified Device Architecture (CUDA)
computing platform. This work also includes several examples
that demonstrate the ability of our technique
