This study proposes a fast rendering method for water droplets on glass surfaces, where the merger phenomenon between two droplets at non-adjacent cells is represented by detecting the collision of their contours and moving them closer into a single water droplet after the collision detection. The appearance of water droplets is efficiently rendered with an environmental mapping technique, a generating method of texture images using the framebuffer object function, and plotting these images using the point sprite function.
