Disney: Creating the perfect digital tooth requires something that resembles a medieval torture device. Graphics in video games and movies have 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 one system specially designed to capture the visual properties of human teeth so they can be realistically reproduced in computer graphics”.
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 facial blockages, we retract the lips and cheeks using an OptraGate lip retractor."

The visual effect of this tooly described so elegantly in scientific language, it looks like something straight out of a horror movie.
However as soon as the researchers manage to get them data them, they run them through a complex series of mathematical equations to fit their digital templates onto the volunteer's real teeth. Once this process is complete, the digital chompers can be processed and incorporated into movies and video games.
