    I have been reading papers lately on the early history of computer
    panning/zooming around the 3D models. I'm really interested in the
    period before 1985.

    The papers I have been reading store the data in a matrix then use an
    algorithm to do the transform and produce a new set of 3D coordinates
    to render the image.

    This type of thing is now routinely done in CAD programs and in
    computer/video games.

    Could anyone here suggest the seminal papers or really complete reviews
    on the subject circa 1985 or before?

    Thank you so much.

    The ESL "Kludge" display system on the 7094 at MIT's Project MAC/CTSS
    was a line drawing (vector) display system rather than a raster
    scan system. It had a matrix multiply between the line drawing
    hardware and the display hardware. You could rotate (and scale)
    the wire-stick models by just updating the matrix rather than
    the whole display list.

    That was mid 1960s.

    That is great information. I found a wonderful site about that. Thank

    I was really hoping for a paper that showed the state of the art around
    80-83 if anyone has additional ideas.
