Rotating Hypercubes

The discussion of dancing pendulums in javascript at SSSF led onto Rotating Hypercubes, which resulted in this javascript animation by forum regular mollwollfumble:

4D Rotations (click to view in a new window, right click to download javascript file)

See the SSSF thread for discussion on how to do these things in javascript.

Update 27-Jun-11:

As noted in the comments, we had covered rotating 4D hypercubes here before (in a spreadsheet provided by Lori Miller), and I’d forgotten all about it!  The video link below shows what it looks like, but for a good look at the workings, click on the link: Hypercube.xlsx, then download the file, and have a look at the range names.

    Nice demo, the lighting effects add to the realism.

    In the recent Excel hypercube download I had trouble recalculating in Excel 2007, maybe this is due to being saved on the skydrive?

    To make animation automatic, just enter in the immediate window “do:[c6]=[c6]:doevents:loop”. Changing 4D settings creates some mind-bending rotations in which the inner and outer cubes change position with each of the other six “3-Cells” (analogous to configuration changes of 2D faces in 3D rotations).

      Lori – I downloaded the file, and didn’t have any trouble running it, but then I started a video screen capture program (CamStudio), and the F9 key stopped working. I got it to work eventually with a short VBA routine:

      Sub Animate()
      Dim i As Long
      For i = 1 To 1000
      Next i
      End Sub

    Hi Lori

    I’m sorry to say I’d quite forgotten about your hypercube when I wrote that post. When I get some time I’ll have a look so we can add an in-Excel animated hypercube to the list.

    Also the gif animation at the bottom is taken from another web-site, so I’ll edit the post to show the link.
