Dynamics that follow animation

[hoi]

Hi guys,

This is my first post to Odforce, so hopefully I don't sound to dumb.

I'm trying to figgure out how to get a dynamic object to follow the position from the animation.

There is a very fast way in C4d to get this behavior, thats called follow position / follow rotation.

And because they use Bullet also, it should be possible in Houdini.

This is the only videoexample I could find, already old (still called followAnimation back then)

It starts at 6:19 min :

First I thought about a "multisolver", that tries to mix the outcome of the dynamics with the original animation.

But now I think it's more of a directional/elastic "force" to the original position (the position of the object without dynamics applied).

I hope it's a little bit clear what I mean. its hard to explain.

But nevertheless its a very nice way to direct your dynamic objects, also because you can animate the force/strenght how much it will follow the animation.

Can anybody guide me in the right direction ?

Thanks in advanced!

Have you looked at Peter Quint's video "Dynamic Spheres", on Vimeo?

I think it might be of some use.

Check out the example from the Houdini Documentation:

Also you could animate your objects, generate velocity with a trailSOP, then have a a DOP start on a later frame, using the velocities to keep the motion etc...

There was a post a while ago by Macha that I think achieves what you are looking for.

Hi guys!

Thanks for the quick replies.

Dynamics spheres I've seen awhile ago. Need to see that one again as a freshup.

Macha's post/example was exactly what I was after!

Thanks for the link.
