Pixel data processing system and method for producing a spatial multiplexed image of a 3-D object for use in stereoscopic viewing thereof. The pixel data sets of each pair of first and second perspective (e.g. left and right) images of a 3-D object, are stored in a first and second memory arrays. The pixel data sets of the first and second perspective images are processed in accordance with complimentary spatial modulation functions, so as to produce third and fourth pixel data sets representative of first and second spatially modulated images consisting of first and second pixel patterns, respectively. The pixel data sets of the first and second spatially modulated images are stored in third and fourth memory arrays. The pixel data sets of the first and second spatially modulated images are processed in accordance with a spatial multiplexing function, so as to produce a fifth pixel data set representing a spatially multiplexed image (SMI) of the object. The pixel data set of the spatially multiplexed image is stored in a fifth memory array, and is then translated into a set of vector quantities that are used to graphically present (e.g. record or display) the spatially multiplexed image for viewing through an optically transparent micropolarization panel and a pair of passively polarized spectacles.
