摘要： A method of using a computer to generate virtual autostereoscopic images from a three-dimensional digital data set, includes establishing a first point of view and field of view of a subject volume including a region of interest. The method includes reading at least one scene parameter associated with the field of view of the subject volume. The method includes determining a second point of view offset some distance and along some vector from the first point of view based on a value derived from at least one scene parameter wherein said second point of view at least partially overlaps the first field of view and wherein said first and second points of view create a view plane with perpendicular orthogonal views of the subject volume. The method also includes generating and storing images and relevant metadata from said first and second points of view. The method includes displaying the stored images by alternatingly displaying stored images from said first and second points of view at a rate of between 2 and 60 cycles per second. Additionally, one or more transformations can be performed on the alternatingly displayed images that brings some desired point in the region of interest of both images into a converged critical alignment wherein the said region of interest appears three-dimensional to a viewer on an standard two-dimensional unaided display.
