View Full Version : Animating DNA

I'm in a pickle here, trying to animate something or find a previously animated scene file of it.

I am working on an animation involving human DNA, formed in a double helix.
It will at one stage unzip itself from one end, split apart, and new genomes will join together to form a new ladder of DNA.
I've previously worked on things with DNA before, but never this complicated. Modelling it was easy enough, with two spirals forming the crvs for 2 surfaces representing the curved edges of the double helix. The spirals aren't frozen so it is possible to unwind the entire strand at once. The "fun" part is now working out how to do it progressively creating the unzipping effect.
Here are a couple of references of what I'm on about: The first shows the new dna being built quite nicely, the second shows the unzipping effect. Both show way too much detail for the curriculum being taught, so ignore the huge pink thing and other 'machines'.

Has anyone got any pointers as to how they'd go about rigging this kind of thing?
