This Is A 3D Computer Animation Of 4D Shapes From 1965

Computer animation may be a lot better than it used to be, but it's been around for quite a while. This is an example of one of the older bits, dating way back to 1965, and it features some "4D" shapes. Oh, and it's also in 3D. Just cross your eyes.

Most of the work done to make this quick little video was done on a IBM 7094 by A. Michael Noll, who whipped that second 4D trick back out for Bell Lab's Incredible Machines. Sure, the cross-your-eyes for 3D gimmick is a bit primitive, but it doesn't require any kind of extra gadgetry. And, lets face it, it's only marginally less obnoxious than the stuff we've got now.

    Cute. It's an attempt to use a 2D medium (video) to make a "3D" animation of the "shadow" or "projection" of a shape with 4 spatial dimensions. If you count time as a dimension, then you could market it as 5D!

    If you'd like to understand what that shape in the video is, the best explanation I've come across was written in 1884. Flatland: http://www.geom.uiuc.edu/~banchoff/Flatland/

    The second half of the video Made me feel quite I'll, I think my brain was just rejecting it!
