A method for transforming extended video data for display in virtual reality processes digital extended video data for display on a center screen and two auxiliary screens of a real extended video cinema. The method includes accessing, by a computer executing a rendering application, data that defines virtual screens including a center screen and auxiliary screens, wherein tangent lines to each of the auxiliary screens at their respective centers of area intersect with a tangent line to the center screen at its center of area at equal angles in a range of 75 to 105 degrees. The method includes preparing virtual extended video data at least in part by rendering the digital extended video on corresponding ones of the virtual screens; and saving the virtual extended video data in a computer memory. A corresponding playback method and apparatus display the processed data in virtual reality.
