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.
