Rolling

Here's a post of one thing that worked.

interesting.... cool looking

[starwarsguy]

looks pretty good. i've never tried doing something rolling up, but now that i think about it, it sounds like quite a challenge. good work!

[jamagica]

How Did you do that?!

[MATrickz]

heh, thats pretty cool

[ddustin]

I created a "mat" with 32 bones.

 

Next I created a spiral shape with 32 bones.

 

I rotated the spiral shape while feeding the mat into it.

 

As each bone from the mat intersected with a bone on the spiral, I constrained the bone on the mat (say bone 1) to a bone on the spiral (say bone 1 target). You would also constrain the bone 1 to orient like bone one target so they roll together.

 

The better the spiral (convoluted shape) the better the roll up.

 

It's still not something I'm satisfied with.

 

I also experimented with a bunch of pose sliders and smart skin. It has promise, but it's still not as realistic as I would like.

 

Here's the prj if you want to play with it. There are some doubled splines, but I was just working on the principle.

 

Foam Rolling

Philip sent me a prj that used a boolean cutter and a roll to give the illusion of rolling up (thanks Phillip).

 

Still working on it.

 

Edit: Think the link is fixed Edit again: no it's not, so it's attached.

It's a nice effect David.

 

Next time you post it could we see it from more than one angle, that'd be cool.

 

Keep posting.

This is what I came up with. Anything you can use?

Aww...man, now how was that done!?!

[ddustin]

I can't view it.

 

BRB I'll update my quick time.

EDIT: I still can't view it. The screen is just white.

 

How large is the file?

 

EDIT 3: I copied the file to my computer and I get a notice that I don't have the right compressor.

Sorry about that. It is an MPEG-4 movie on 175 kB.

 

Try this one instead (Sorensen3 363 kB):

Just muscle animation in an action. Nothing fancy.

[ddustin]

Aaver,

 

That's exactly what I need to do.

 

It's outstanding!!!!

 

Can you post the project?

 

Thanks,

David

Aaver,

 

Thanks so much for the file, it'll save me a ton of time.

Aaver,

 

How does it work?

 

There is only one bone.

As I said, this is only a simple muscle animation in an action; very static. The use of it is shown in the chor example.

What is it that you want to do with it?

[ddustin]

Sorry I haven't played with muscle animation at all.

 

If I understand it correctly you manipulate the CP's in the action to make the part roll.

 

I realize this sounds obsessive, but I woke up this morning at 3:00 AM thinking about how to do it.

 

As far as "what is it you want to do with it", I need to roll up a perfectly flat rubber material, with no contours.

 

This is so cool.

 

David

 

Edit: Yup, you manipulate the CP's in the action and progressively roll the part up.

Thanks for your help.
