Challenging animation - how would you approach this?

[Anti-Distinctlyminty]

Hi all,

I've been trying to come up with a way to animate this

(ignore the high frequency jiggling movement)

 

I have also attached a quite amazing MS paint schematic, but basically the animation is this:

1. Have my DNA object following a curve (probably using the wonderful free tool https://www.orbolt.com/asset/animatrix::pathDeform::1.00)
2. Other objects (histones) must come in and attach to specific points on that DNA.
3. It then must coil up, all the while the histone pieces have to remain on exactly the same spot on the DNA.
4. Finally the whole unit is coiled up nicely.

 

I really do not know what way to approach this. I think I somehow need to get the histone pieces to be constrained by / attached to the curve, but I cannot find a way to do this (the rivet node seems way to cumbersome to be useful in this). Also, I cannot use dynamics :/

 

I have attached my current hip file which has the model and correctly coiled curve around the model.

 

Any ideas would be most welcome as I'm quite stumped

Here are some of my musings on playing around with DNA strand concepts.

Maybe there is something of use there?

Hi Atom,

It's really the animation that I'm finding difficult rather than the modelling part. 

I cannot find a way to constrain a fixed point on a curve to a fixed point on a mesh :/

It's just a crude setup but i hope that it help you.
