Better visuals in the coming generation of games may come courtesy of Mother Nature. Computer graphics researchers at the University of California San Diego were looking for way to create better animation and their work took them into the colorfully iconic rainy-day phenomenon. The results reveal exactly how rainbows manifest and includes new findings on the shapes of raindrops. Now, those researchers claim that simulations of different kinds of rainbows are possible. Those simulations will apparently help create more realistic graphics that will wind up in future video games and movies. Hopefully, this means a lot less grey and brown in the interactive experiences of tomorrow.
