Disney: Creating the perfect digital teeth requires what looks like a medieval torture device. The graphics in the videogames and films have now become very realistic, and the methods used are becoming more and more complex.
Below we will see what Disney researchers do in their quest to create the perfect digital teeth.
"The ideal appearance of the teeth depends on the social and cultural context of the subject, as well as his age," say Disney researchers in a paper entitled Appearance Capture and Modeling of Human Dental.
“We present a system specifically designed to capture the optical properties of human teeth so that they can be realistically reproduced in graphics computers".
To record how the teeth and the oral cavity are seen, Disney researchers needed volunteers who needed to remain stationary as they shattered 54 on their faces with different lights while a camera was constantly shooting pictures.
"To do this, we have a stabilizing neck brace, a headband and a rigid object to bite, which also helps to separate the upper and lower jaws," the paper said.
“To minimize blockages from the face, we retract the lips and cheeks using an OptraGate lip retractor”.

The visual result of this tool, so stylishly described in the scientific language, seems to have come out of a horror movie.
But once the researchers manage to get their data, they run it through a complex series of mathematical equations to match their digital templates to the volunteer's real teeth. Once this process is complete, processing and embedding of digital chompers into film and video can begingamea.
