Simulating a scroll opening

[menoz7]

Hi,
I need to simulate a scroll opening up. Sort of like a carpet getting rolled up. The paper needs to open up from the center and leave the ends still rolled up like your typical scroll.

Thanks again

I have a couple of ideas about this but, I see your problem... my first would be to:

1. animate the rolling up of the scroll and then reverse the animation to make it appear as if it was unrolling.

2. depending on the angle in which you are viewing it and how much detail you are using on the scroll you could (in simple form):

take a plane with high division and key frame the rolling up of the scroll and then like i said... when your finished play the movie backwards.

Heya,

haven't tried this yet.. but did you try the non-linear deformers?

I tried the bend deformer but could not get the rolled up look on the ends. Then I applied a lattice to each end with a bend deformer but still could not get it to work.

I was able to get this to work by using multiple bend deformers (3, actually).

The first bend deformer was used to simply bend up the paper just a little bit.. this allows the paper to roll up on itself with some "thickness". (I used a curvature of .04.. that seemed to work pretty well).

Then the second and third bend deformers were used for opposite rolls. Then for the second and third bend deformers, I gave one a high bound of 0, and the other a low bound of zero. On the one with the high bound of 0, I set the low bound to 10, and the opposite on the other bend deformer. Then set the curvatures up to 10 on each one, and move them apart until the roll looks correct. If you move the bend deformers, you can see the paper unroll.

hope that helps!
