Rubik 's Cube 2004-05-05 - By Chris Marshall

Actually, the more I think about it, I have a feeling that you need a
seperate null for every turn you want to make. So if one of the squares gets
turned 10 times, it needs to be parented under 10 nulls.
Sounds bad, but at least you know that the rotations won't go wierd on you.

try to keep track of all your nulls in your scene, good luck ;-)

Maybe!
Anyway, off the top of my head because I can't get to XSI at the moment,
you need to parent each cube under 3 nulls, each for x,y and z. Then
when you do your turns, you need to select the correct null on each of
the 9 little cubes you're rotating.
Something like that.

It wasn't a gimbling, 3 axis, local rotation thing, was it Chris?

Well, I had to animate one of these things recently and it is a
nightmare. You do a couple of turns and all works fine. Then you set-up
the third turn and key it, still it all looks fine. But when you play it
back, everything goes pair shaped in a big way. The rotations get all
buggered-up and it's a real head-blower to figure out.
In the end I managed to get about 5 or 6 turns completed. I'll dig out
the scene and re-cap on how it was parented.

have you opened up a Rubik's cube to see how it works? It's quite
elegant and you should be able to make it work in Xsi, after all,
there's nothing in there that attaches and detaches cubes to and from
each other.

I'm trying to think of a good way to animate a Rubik's cube. The most
obvious way that I can think of is to manually turn off and on a bunch
of constraints to nulls. Has anyone come across this before? Any tips or
suggestions?
Thanks.
