Study of an Analog Computer System for Reconstruction of Three-Dimensional Figures from Planar Projections
E. Hirsch · IEEE Transactions on Instrumentation and Measurement · 1967
An electronic analog computer remapper (reconstructing, mapping, and projecting analog computer) is studied, capable of reconstructing figures, graphs, shapes, etc., in three- or higher-dimensional spaces from their two-dimensional projections given in the form of drawings, slides, or photographs. The pattern of the reconstructed figure can then be distorted, remapped according to certain transformations, reprojected on desired planes to form new, differently parallaxed pictures of the reconstructed figure, or simply stored in a digital computer memory as a list of coordinates or vector components of points in space, together with their corresponding brightness values.
