This article describes the developing fields and techniques related to three-dimensional objects. The improvements of 3D display devices and technology let us feel the most real perception of objects in virtual world. In order to facilitate these equipments, it needs a lot of image and video data to processing behind. But, the storage and transmission of this tremendous amount of data is very critical. Thus, the new generation of video coding standard - MVC(Multi-view Video Coding) is introduced to compress these video data. We will describe these topics in three parts: 3D display devices, multi-view video coding, and transmission and storage of these data.
