An apparatus for delivering virtual reality data portions to a client device, including a processing unit configured to perform the following in each one of a plurality of iterations: (1) receive from a network a current orientation data indicating a current orientation of a client device, (2) apply a rotation to a segment of a sphere defined in a virtual reality (VR) video file according to the current orientation, (3) crop from the rotated segment of the sphere in an equirectangular projection format an extended field of view (EFOV) frame in the equirectangular projection format according to the current orientation, and (4) instruct the network to transmit the EFOV frame to the client device.

Provided is a method for realizing 3D display, comprising: acquiring an image having eye space information of a user; acquiring eye positions of the user according to the image having the eye space information of the user and by means of a displacement sensor that operates independently relative to a main control chip of a 3D display terminal; and generating 3D display content according to a to-be-displayed image and the eye positions of the user. According to the present disclosure, the displacement sensor that operates independently relative to a main control chip of a 3D display terminal is used to directly process the acquired image having eye space information of a user, instead of processing the image by means of the main control chip of the 3D display terminal. Further provided are an apparatus for realizing 3D display and a 3D display terminal.
