Reslicing

A movie can be thought of as a three-dimensional array of pixels - horizontal, vertical and time. If you have such a three-dimensional array of pixels, there are three different ways of turning it into a movie - three different dimensions that you can pick as "time". For movies of real things this probably isn't a very interesting thing to do, but for movies of mathematical objects like the one I made yesterday, there may be mathematical insights to be gained from "reslicing" a movie.

So, here is yesterday's movie with the x and time coordinates swapped:

Higher resolution version (8Mb 640x480 DivX).

And here it is with the y and time coordinates swapped (and also rotated to landscape format):

Higher resolution version (8Mb 640x480 DivX).

    What a co-incidence for me to find this blog! (found it via mathart community on LJ)

    I have done exactly what you express above, but with 'real' day-to-day videos - and the effects can actually be interesting....

    Alex, that's awesome - thanks! I take it back - this is an interesting thing to do with movies of real things.
