Method for displaying a three-dimensional scene on an auto stereoscopic monitor, wherein a) a number N of basic images (21, 22, 23, 24, 25) of a three-dimensional scene are pre-determined, which each show the three-dimensional scene from different viewing angles, b) a basic image mask each (31, 32, 33, 34, 35), respectively with the size of a native monitor resolution of the auto stereoscopic monitor or a part area of the auto stereoscopic monitor is pre-determined for each of the basic images (21, 22, 23, 24, 25), c) the normal distance (d') of the viewer of the auto stereoscopic monitor is calculated as normal to the monitor level of the auto stereoscopic monitor and characterised in that d) a stretching factor is calculated depending on the normal distance (d'), and e) the individual basic images (21, 22, 23, 24, 25) are weighted pixel by pixel or subpixel by subpixel with the respective image mask (31, 32, 33, 34, 35) allocated to them, and are subsequently added up to a grid image, f) the grid image calculated in this way is displayed on the monitor of the auto stereoscopic monitor, g) the basic image masks are stretched or compressed according to the stretching factor in the direction of the horizontal image axis and are transmitted to respective image masks (31, 32, 33, 34, 35) by means of interpolation, wherein the respective image masks (31, 32, 33, 34, 35) have the same resolution and width as the basic image masks, and h) the image masks produced from the basic image masks through compression and/or stretching are centred horizontally, so that the horizontal centre point of the centred image masks matches the horizontal centre point of the basic image masks. a) a number N of basic images (21, 22, 23, 24, 25) of a three-dimensional scene are pre-determined, which each show the three-dimensional scene from different viewing angles, b) a basic image mask each (31, 32, 33, 34, 35), respectively with the size of a native monitor resolution of the auto stereoscopic monitor or a part area of the auto stereoscopic monitor is pre-determined for each of the basic images (21, 22, 23, 24, 25), c) the normal distance (d') of the viewer of the auto stereoscopic monitor is calculated as normal to the monitor level of the auto stereoscopic monitor and characterised in that d) a stretching factor is calculated depending on the normal distance (d'), and e) the individual basic images (21, 22, 23, 24, 25) are weighted pixel by pixel or subpixel by subpixel with the respective image mask (31, 32, 33, 34, 35) allocated to them, and are subsequently added up to a grid image, f) the grid image calculated in this way is displayed on the monitor of the auto stereoscopic monitor, g) the basic image masks are stretched or compressed according to the stretching factor in the direction of the horizontal image axis and are transmitted to respective image masks (31, 32, 33, 34, 35) by means of interpolation, wherein the respective image masks (31, 32, 33, 34, 35) have the same resolution and width as the basic image masks, and h) the image masks produced from the basic image masks through compression and/or stretching are centred horizontally, so that the horizontal centre point of the centred image masks matches the horizontal centre point of the basic image masks.
