hi , I am driven by need to deform the mesh of a open hand and bring it to a close fist position
i was thinking about using flow along surface as a deformation cage. Mi idea was to model the deformed surface by using quad remesh/SubD gumball functionality and then flow the mesh along the subD surface basically as shown below
problem is that flow along surface does not accept SubD object and polisrurfaces either .
any suggestion on possible solutions inside rhino? would the command flow along subd make sense ? thanks

A few more threads with examples using the tool Martin linked above:
I did experiment a bit with using the Grasshopper cage morph stuff I posted here for this.
I warn that this is far from a conventional skeletal posing/animation workflow like you might use in Blender/Poser etc. and it is still far from easy - you have to manually move the cage points in the right way to not stretch or squash the form too much - and for very dramatic changes in pose it will probably break down.
Anyway, here it is if you want to try:

Is there any chance to have cages with controlpoints x,y,z that do not start as a box, or that can be deformed before and without applying the deformations to the child? I know that is possible with surfaces as cage, but they have only U and V points.
I suspect this is fundamentally not possible, but I am not sure. This is a very old wish of me.
Something like this?
This is with the mesh cage morph component which I shared a version of here .
I’d like to make this into a Rhino command too (once I’m done with the multipipe, fuse and wrap commands!)
