ABSTRACT:
A method is provided for obtaining images for use in displaying a three-dimensional illusion which includes the step of obtaining first and second images of a subject volume having foreground and background portions with the points of origin of those images located in a first plane which includes left and right points of origin of an observer of the subject volume and which is normal to the optical axis of that observer. The first and second points of origin are also respectively located equidistant above and below a first line interconnecting the left and right points of origin and are located along a second line which is normal to and bisects the first line. The first and second optical axes are aligned to converge in a second plane parallel to the first plane which includes the foreground portion of the subject volume within the field of view of the observer which is closest to the first plane. A support apparatus is provided for using one or two imaging devices in implementing the method of the subject invention and an alternative support apparatus is disclosed which incorporates a teeter-totter arrangement to automatically provide for maintenance of convergence of the optical axes in the second plane upon adjustment of the effective first and second points of origin above and below the first line connecting the left and right points of origin of the observer. Image recording medium containing images produced by the above method is also disclosed.
