Digital Effects Inc., "Cards, Cube, Bottle," 1977. This is one of the very first outputs of the Digital Effects 3D Visions software, made prior to the company acquiring a motion picture output device. The image is programmed in APL and Fortran, and this output is achieved via running the program on an IBM 370 computer and outputting on a Calcomp pen and ink plotter at Syracuse University. Donald Leich, David Cox, and Judson Rosebush contributed to building the objects in the computer, and writing the software to display them in perspective with the hidden surfaces removed. The algorithm uses a scan line approach, easily apparent in the drawing. There is no shading calculated in this image.
