ABSTRACT:
A method for processing nodes in 3-dimensional (3D) scene and an apparatus thereof are provided. The method includes the steps of identifying a 3D mesh node having 3D mesh information representing a 3D shape which is formed by constructing faces from vertices among nodes contained in a 3D scene to be processed; and encoding or decoding the identified 3D mesh node. Also, the method includes the step of transmitting or storing the 3D mesh information of the encoded 3D mesh node through an independent stream separate from the 3D scene description stream. According to the method, a node representing 3D mesh information having a huge volume of information in a 3D scene can be efficiently encoded and decoded so that the 3D scene can be efficiently transmitted and stored. By transmitting and storing 3D mesh information of a node representing encoded 3D mesh information, through an independent stream separate from 3D scene description information, the entire 3D scene cannot be affected even though encoded 3D mesh information has a huge volume.
