Rubik's Cube Effect in AE

Postby DarkEclipseStudios » Tue Jun 02, 2009 1:55 am

I found
http://www.animemusicvideos.org/members/members_videoinfo.php?v=165013 this really amazing amv and there was a rubiks cube effect in it. (its on utube too) anyways i bet it was done on AE, in which i have, so I would love to find out how to do it! ^_^

You just position things around in 3d space. Then you can precompose or use parenting to group certain things together. Then you just... move them.

the parenting is going to be an issue when you rotate different sets of cubes. i imagine you would need to have a different parenting structure for rotations on each axis... you could fake it with 3 cubes set up appropriately and cut between them.
:? no wait, i just cooked my brain. i will try this later o:

Here you go. Unless you want to get into actual expressions your best bet is to precomp your individual sliders. I'd say just use that cube guide as a base.

Stuff like rubik's cubes are.. extremely hard to get to work in any piece of software. And AE probably isn't the best option. As I can't see the video linked I can't tell you what they did. Nor do I know exactly what you're trying to recreate.

rigging a fully functional one for animation would be interesting.

Here is a project file for a nice, NON-FUNCTIONAL rubik's cube.

I am willing to bet that every rotation is done standalone rather then having it being fully rigged. It would get way too complex to rotate stuff along both X and Y without switching the parent out at every rotation. The individual rotations aren't the problem but I think looking at making it fully rigged is over complicating things. I mean its not entirely impossible but doing each rotation separate with only 1 rotation axis would be the way to go.

If you want it to look good, you would probably need to use an actual 3d application, like how this one was made: http://tinyurl.com/bmfq3v

I was thinking of trying to recreate something like this one day, but I probably never will.

Only possible problem I see with that cube is the rounded edges and possibly the reflections. Granted the reflections could always be faked. Rounded edges will be a little harder. But to be honest Alan that doesn't seem like it would be too complex, considering it only does one rotation at a time.

seems like a whole lot of work :\ there are quite a few number of rotations too :(
i would bet it was a 3d app as well, being fully rigged
of course not using the specific link Zar posted, but if you had a 3d animator, i bet it would be easier to recreate that whole scene, than doing one axis rotation at a time.
i duno though, it did look pretty sharp :\

even if it was done in 3d, how would he place the clip on the side of the cube?
color the sides of the cube, keyed it out and then match corner points?

the one in the vid was clearly done in ae, and there's no reason to believe it's fully rigged.

however, rigging one in ae would be a fun challenge if you're up to doing the math...

that said, rigging one in c4d is pretty straightforward, since you can dynamically change the parenting.

you would mark each block with compositing tags, and export a maya scene file (pretty much any 3d app can do this), this can be imported into most compositing apps (including ae), and would give you a comp with a camera, and a set of labelled nulls in 3d space. the nulls will have the animation from the 3d scene baked, so you just parent your video squares to the nulls and align them in 3d space. you would also export an object buffer matte from your 3d app so you have something to occlude your video layers as they move out of sight.

Hey guys I just talked to the guy who made it, and he said he just made 3D cubes and moved them frame by frame ON SONY VEGAS PRO! he said it took forever. 0_0 I bet lolz

Vegas would follow the same basic principles as what we're getting at. Only difference being that its pardon my language fucking retarded to do in there. Simply put the way we're getting at would cut the workload down to about 1/5th if not less.

Mind you what Blabbler is talking about now is the fully decked out cube Zarx linked =P
