Apparatus and method for realistically expressing teeth

摘要

A method and apparatus for realistically expressing teeth performs rendering on a shape model of the teeth using a hybrid normal map based on materials and characteristics of the teeth in order to more realistically express the teeth.

主权项

1. A method for realistically expressing a set of teeth, the method comprising:
acquiring a shape model of the teeth; generating a hybrid normal map adjusting a light pattern in a virtual light stage, wherein the hybrid normal map is used to represent materials and characteristics of the teeth, and wherein the virtual light stage is used to represent optical characteristics on the shape model; and performing a rendering on the shape model based on the generated hybrid normal map, wherein the generating of the hybrid normal map comprises:
generating a diffuse normal map using the virtual light stage, wherein the diffuse normal map is used to represent a diffuse reflection occurring in the shape model;generating a specular normal map using the virtual light stage, wherein the specular normal map is used to represent a specular reflection occurring in the shape model; andgenerating a hybrid normal map for the shape model, using the generated diffuse normal map and the generated specular normal map.
