American Museum of Natural History Exhibit T.Rex with simulated Tetrachromatic Vision

Today at March 11, 2019 the American Museum of Natural History in New York at Central Park officially opens up their new exhibit T.Rex: The Ultimate Predator through August 9, 2020 and it contains some of my work, as T-Rex was supposed to have tetrachromatic vision, as those were the ancestors or our today's birds, which have tetrachromatic vision.

For demonstrating this to its visitors, my Rudbeckia hirta flower shots in 3D stereo human vision as well as in simulated tetrachromatic vision were used.

I'm always amazed about the differences in our human trichromatic color perception and how that very same flower would look like, if seen through tetrachromatic eyes, being able to also see ultraviolet (UV) light, invisible to us humans!

Hence why I developed a method to simulate that, by mapping a 4-dimensional tetrachromatic color space into our trichromatic 3-dimensional one.

I have written more about this flower HERE and about tetrachromatic vision HERE

Stay tuned, more will follow on that fascinating subject...
