A relative position of a given eye of user(s) is determined with respect to a semi-reflective surface of an optical combiner, using a tracker. A given reflection region is identified on the semi-reflective surface from which light emitted by a light-emitting surface () of an autostereoscopic display is reflected toward the given eye. A given three-dimensional (3D) view frustum corresponding to the given eye is determined. For a given virtual depth at which graphical element(s) is/are to be presented, a frustum cross-section of the given 3D view frustum is determined at the given virtual depth relative to the given eye. Spatial anchor(s) is/are positioned at predefined position(s) on the frustum cross-section. A position for the graphical element(s) on the frustum cross-section is determined relative to the spatial anchor(s). A given image for presenting the graphical element(s) to the given eye, is determined, the graphical element(s) being positioned at the determined position.
