Title:
ENCODING METHOD, DECODING METHOD, APPARATUS, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/155779
Kind Code:
A1
Abstract:
Disclosed in the present application are an encoding method, a decoding method, an apparatus, and a communication device. The encoding method in the embodiments of the present application comprises: on the basis of a space included angle of adjacent triangle patches in a three-dimensional mesh, an encoding end determines in a first space range vertexes to be sorted, the first space range being a space range where a target vertex of a triangle to be encoded in the three-dimensional mesh is located, and the vertexes to be sorted comprising the target vertex; and the encoding end sorts the vertexes to be sorted so as to obtain sorting information of the target vertex; and on the basis of encoding information corresponding to the sorting information of the target vertex, the encoding end obtains the encoding information of said triangle.
