IK solver with arced joint chain

Hi All,

 

does anyone know if a IK solver that can generate an arced joint chain?

 

I am trying to add a nice arc to a spine but I still need to hit a specific position in space for the end of the joint chain.

This is for a first person character driven by a VR HMD. So the head needs to hit the position of the hmd but I still want a nice arc to the back.

 

In maya there's the 'spline ik' that could probably do this but I am working inside Unreal 4 and there is no such thing.

But I haven't found any code examples either.

 

Any ideas anyone?

 

Cheers

Fred

This should just be a matter of adding joint constraints to the bones in the spine, if I'm reading you correctly. Most real-world IK implementations can handle this AFAIK.

Hmm...what do you mean by joint constraint?

As soon as I 'manually' constrain any of the joints below the tip joint(that needs to hit the hmd pos) in position or orientation I will affect the position of the end joint, as solved by the UE4 'two bone ik' solution.
