RENDERING IMPROVEMENT FOR 3D DISPLAY

A method of creating image data, the image data suitable for use with an autostereoscopic display which may be modelled as comprising a 2D display and a switchable aperture array, the method comprising taking a plurality of samples of a 3D scene using a display plane and an aperture plane modelling the autostereoscopic display, each sample taken for the combination of a pixel on a 2D display of the modelled autostereoscopic display and an aperture of the switchable aperture array of the modelled autostereoscopic display, wherein the line along which the sample is taken for a combination of a pixel and an aperture passes through substantially the same point of the aperture for all samples for a particular aperture and wherein the line along which the sample is taken for a combination of a pixel and an aperture passes through substantially the same point of the pixel for all samples for a particular pixel.
