We present NIMBLE, a non-rigid parametric hand model that includes bones and muscles, bringing 3D hand model to a new level of realism. By enforcing the inner bones and muscles to match anatomic and kinematic rules, NIMBLE can animate 3D hands to new poses at unprecedented realism.

This model and code was developped and used for the paper NIMBLE: A Non-rigid Hand Model with Bones and Muscles for SIGGRAPH22. See project page

It reuses part of the great code from manopth by Yana Hasson, pytorch_HMR by Zhang Xiong and SMPLX by Vassilis Choutas!
