Procedural Animation of Moment Freezing

Abstract

This study proposes a procedural animation method of instantaneous state transition by cooling water. The fluid simulation of this method is performed using the FLIP (Fluid-Implicit Particle) method, in particular, using the viscous term of the Navier-Stokes equation, which is the governing equation, and updating the temperature change at each time step. To stop the movement of the fluid and create a stationary state. Temperature data is updated by using volume data (information group with volume) and particle data (information group of point aggregates. Temperature transition is added to both data, and state transition with free shape is possible by interference. Become. In addition, by allowing only a part of the fluid to interfere, it is possible to represent a state in which solid and liquid coexist in one simulation.
