Real Rendering of Lips by Computer Graphics

Abstract

Recently, it is important to make or send human face images by computers in the intelligent information communication, man-machine interface and so on. Computer graphics techniques to render faces or hair really, therefore, are studied at many laboratories. In order to make a photographical face image, especially among elements of a face, it is important to render lips naturally. The present paper describes a method to render human lips, especially female rouged lips with sizzle feeling. At first, an image processing method to make three dimensional data of lips from several photos of female lips is proposed. Next, a rendering method to make real images of lips from the three dimensional data is described. In this process. a technique to represent fine wrinkles on lip surfaces by scattering reflection rays was applied to get realistic image of female lips.
