I can get an articulated hand model that can be easily posed in Rhino??
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:
deformable_hand.gh (4.2 KB)
deformable_hand.3dm (401.5 KB)

Here come the middle finger screenshots

hah, my thoughts exactly! I’m downloading that and putting a middle finger in my model.
Not everyone is so rude!
Some just want others to live long and prosper
Also, forgot to say - when opening up that gh definition, you’ll want to click the button once to initialise the weightings

Thanks very much! The Rhino forum is truly a class act. Thanks all
Hello,
How did you reconstruct the hand so cleanly? I would like to reconstruct hands by simply inputting lines and spheres.
I noticed that in your file you have a very clean hand mesh. Was this constructed based on a skeleton with spheres?
This is what I currently have:
deformable_hand (3).3dm (390.4 KB)
deformable_hand (2).gh (20.1 KB)
In my example file the cage quad mesh was manually created, but the higher resolution hand mesh being deformed was from a 3d scan.

Thank you for your response. My goal is to create a 3D hand model from a 2D hand image. The reconstruction does not need to be perfectly accurate. I was considering using a “fatten” method or deforming an existing hand mesh to match a hand skeleton that i extracted from the image.
Do you have any suggestions on how I could achieve this 3D mesh?
not sure if rhino is the right tool - animation software will have tools for stuff like this.
for example Animation & Rigging — Blender
… but I am not an expert in this field
