Abstract Provided is a method for displaying a three-dimensional (3D) image by a device. The method comprises the steps of: transmitting information about a viewport of the device to a server; receiving, from the server, data on at least one second area corresponding to the viewport among a plurality of areas of a packed two-dimensional (2D) image; and displaying a 3D image based on the received data, wherein the packed 2D image is generated by modifying or relocating at least a portion of the plurality of areas of the 2D image which is projected from the 3D image, and the at least one second area is identified based on information on a relationship between an index of each of at least one first area corresponding to the viewport from among a plurality of areas of the 3D image, an index of each of the plurality of areas of the 3D image, and an index of each of the plurality of areas of the packed 2D image. Therefore, it is possible to efficiently transmit data related to a 3D image. 디바이스에 의해 3D(3 dimensional) 이미지를 디스플레이하기 위한 방법이 제공된다. 상기 방법은, 상기 디바이스의 뷰포트에 관한 정보를 서버로 전송하는 과정, 상기 서버로부터, 패킹된 2D 이미지의 복수의 영역들 중 상기 뷰포트에 대응하는 적어도 하나의 제 2 영역에 대한 데이터를 수신하는 과정, 및 상기 수신된 데이터에 기초하여 3D 이미지를 디스플레이하는 과정을 포함하고, 상기 패킹된 2D 이미지는 상기 3D 이미지로부터 프로젝션된 2D 이미지의 복수의 영역들 중 적어도 일부를 변형 또는 재배치하는 것에 의해 생성되고, 상기 적어도 하나의 제 2 영역은 상기 3D 이미지의 복수의 영역들 중 상기 뷰포트에 대응하는 적어도 하나의 제 1 영역 각각의 인덱스와, 상기 3D 이미지의 복수의 영역들 각각의 인덱스와 상기 패킹된 2D 이미지의 복수의 영역들 각각의 인덱스의 관계에 관한 정보에 기초하여 식별된다.
