Computer Scientists from San Diego, Spain, England and Switzerland and Henrik Wann Jensen (Jensen also worked for many Hollywood blockbusters including Avatar) tried to create rainbow digitally. By this effort, these scientists discovered some new phenomenon about rainbow physics. Because of these discoveries scientists are able to emulate phenomena including split-double rainbows and redbows.
The team set up a different simulating technique to understand rainbow physics, they finally want to improve graphics in the animated 3D movies. With various simulations they came to know that interaction between spherical droplets and the light can’t be explained in some rainbows like twinned rainbows. As they went on with the research they found as water drops fall, air pressure falls and shapes it like burger called “burgeroids.” They told that different colours appear because of different sized water droplets.
The advising professor, Henrik Wann Jensen said, “This goes beyond computer graphics. We now have an almost complete picture of how rainbows form.”
