Abstract: A system is for three-dimensional stereoscopic rendering of virtual objects in a scenario by a display screen (S) with respect to which an observer (O) can move. The system overcomes the problems of incorrect perception of three-dimensionality which are present in prior art stereoscopic rendering systems. The system includes a device (20) adapted to detect the coordinates of the respective observation position (OL,R) in a predetermined reference system related to the screen (S), by computing (estimating) the positions of the observer's eyes, and includes a processing unit (10) adapted to generate, for each object point (T), a pair of corresponding image points (tiL,tiR) on the screen (S), which are selectively visible to the observer (O) and are related to the detected current observation position (OiL,R).
