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.
