This research is the study of raindrop rendering. In case of rendering for raindrop in existing games, it is used on sprites images or roughly raindrops images using texture rendering. These methods are similar to the shape and size of all rendered raindrop. That's why players are limitations to provide a sense of reality. To overcome this limitation, this paper proposes a method for generating raindrop considering surface tension and contac angle, the amount of water, implements the raindrop using Unity3D engine. To demonstrate the usefulness of this paper, this paper shows the generated raindrop in accordance with the change in the area and pulling force in surface tension formula. This paper can help to provide the actuality in game in case of rendering the raindrop.
