Abstract

We propose an expression method of CG animation of spinnability, which is one of the characteristics of viscoelastic fluid. The method solves the basic equation of fluid and constitutive equations of solvent and viscoelastic fluid by using MPS method. In addition, surface tension is considered since spinnability is affected by air pressure under the condition that the fluid has free surface. Finally, CG polygons are generated from the particles, which positions are calculated by MPS method, by using marching cubes algorithm, and the behavior of spinnability is animated with three characteristics of thin extension, the thinnest center, and rubber shrink.
