3D MODEL COMPRESSION AND DECOMPRESSION SYSTEM AND METHOD BASED ON 3D MESH SEGMENTATION

摘要

A 3D model compression and decompression system and method based on 3D mesh segmentation are provided. A 3D model compression and decompression method based on 3D mesh segmentation, according to one embodiment of the present invention, comprises the steps of: inputting 3D mesh data; segmenting the inputted 3D mesh data; and compressing, in parallel, at least two segmented mesh pieces by using each encoder instance. Therefore, according to embodiments of the present invention, a 3D mesh is segmented and the segmented mesh pieces are simultaneously compressed in parallel, so that 3D model data can be compressed more quickly than that by conventional technology. In addition, an optimum segmentation algorithm that considers compression speed and efficiency is used when segmenting a 3D mesh, and thus compression is efficiently performed.
