System and method for 3D Model compression and decompression based on 3D Mesh

摘要

A 3D mesh segmentation based 3D model compression and decompression system and method are provided. A 3D mesh segmentation based 3D model compression and decompression method according to an embodiment of the present invention includes: inputting 3D mesh data; segmenting the input 3D mesh data; and parallelly compressing the segmented at least two or more mesh pieces using respective encoder instances. Accordingly, according to embodiments of the present invention, it is possible to perform compression of 3D model data faster than conventional techniques by dividing a 3D mesh and simultaneously performing compression on the divided mesh pieces in parallel. In addition, compression can be efficiently performed by using an optimal partitioning algorithm in consideration of compression speed and efficiency in partitioning the 3D mesh.
