• Resumen

  • Heaven talks about fantasy films creating a lifelike digital faces that are faithful down to individual skin cells. Creating realistic faces is one of the biggest challenges for computer-generated imagery (CGI)--largely because the skin's appearance is the sum of a complex interplay of tiny features and flaws. Ghosh and Paul Debevec of the University of Southern California and their colleagues use a specially developed lighting system and camera, they photographed samples of skin from people's chins, cheeks and foreheads at a resolution of about 10 micrometers, so that each skin cell was spread across roughly three pixels. They then used the images to create a 3D model of skin and applied their light reflection technique to it. The result was CGI skin complete with minute structures like pores and microscopic wrinkles.
