I need to move a foot using Geometry Nodes. Instead of using math functions like sine, I would like to be able to control the movement in a more accurate way.

Movement sequence

I would like to control the y position, z position and x rotation of the foot for each frame.

enter image description here

The geometry nodes that show the body, the foot and the leg.

Any idea how to do it?

Thanks for your help :)

  • $\begingroup$ Hello ! I believe this is an occurence of coming full circle here. I don't think GN was built for this level of precision regarding animation tools, at least it's not there yet. Have you tried using the regular animation system ? Armature, rigging, keyframes ? $\endgroup$

  • $\begingroup$ Thanks for your reply Gorgeous. I wanted to use the Geometry Nodes to try to automate the task. Now I was trying to do it using the GN 'Float Curve'... $\endgroup$

Finally I find how to do it. You must use a GN 'Float curve' for each kind of movement.

One for the 'X' rotation, another for the 'Z' movement and finally one for the 'Y' movement.

And it works !

I leave the file in case it can be of help to someone.
