…In a paper describing the experiments entitled High-Quality Capture of Eyes, the team points that despite the human eye being “one of the central features of individual appearance”, and obviously one that is most expressive, “its shape has so far been mostly approximated in our community with gross simplifications”.
In their new approach — as described in the paper and presented at SIGGRAPH Asia 2014 last week — the team used multiple cameras and different lighting to capture all the intricacies of the human eyeball — the texture variations, colourings, veins and refractions that make it such a dynamic feature, changing every millisecond according to the environment.
They write: “We propose a novel capture system that is capable of accurately reconstructing all the visible parts of the eye: the white sclera, the transparent cornea and the non-rigidly deforming coloured iris.”
Each part behaves differently and reflects light differently, so the team decided they must be dealt with individually. The process also means a break away from the perfection of heroines of old. Eyes are asymmetrical and contain imperfections, the team points out. And most importantly, every person’s eyes are totally different from another’s.
To get enough data, the team used six cameras, including 100mm macro lenses focussed on the iris. Flash lighting using different levels of brightness and coloured LEDs were chosen to get different effects reflecting off the cornea, and actors were asked to lie on the floor wearing a headset during the process. Eleven poses were used all together, and the whole thing took about 20 minutes to complete. Images were stitched together to begin to form the basis of the eye movement — for instance, the team found ten images was enough to get the information to replicate iris deformation, while 140 were needed in total. A facial scanning system designed to reconstruct skin was used to generate the eye model….
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
