概要	We propose a method for simulating glazed frost by computing heat transfers between water droplets and the surrounding air. Motions of air and water droplets are computed based on a FLIP (Fluid-Implicit-Particle)-based fluid solver. Glazed frost is a crystal clear ice and formed from supercooled raindrops that freeze when they hit object surfaces. We propose a method to create an animation of glazed frost formation by taking into account the heat transfer between particles and the outside grids. The time to freeze is calculated by considering the heat flux on the surface of the raindrop until freezing from the adhesion on the obstacles. We propose a technique which is highly compatible for a FLIP method to solve the heat conduction equation and we reproduce the formation of glazed frost.
