Disney research team developed real time texturing technology on characters moving in 3D by coloring 2D pictures.
There was the technology to apply texture from the picture to 3D objects or characters before but this technology allow you to color 3D object in realtime with deformation.
It fills the area you can’t paint on coloring book like backside of the characters by guessing color with look up map and relaxing the color distribution.
