A method and system for generating a stereo pair of images of a 3D virtual space and presenting the images to a user. The system includes a display unit configured to displaying a stereo pair of images to the user and a processor for generating the stereo pair of images. The method of the invention, carried out by the processor includes positioning virtual scenes S1, . . . Sn, . . . SN in the virtual 3D space. The scenes are subjected to a first manipulation and then a left 2D image is obtained by projecting the space onto a viewing surface positioned in the 3D space. The scenes are then subjected to a second manipulation and the right 2D image is obtained by projecting the space onto the viewing surface.
