I ported the TF sampler to torch and wrote a little optimizer to fit face params. It's pretty expressive!!!

My team at Google XR just started open-sourcing GNM, our ecosystem of parametric human models and perception stacks, starting with GNM Head. Exciting to see the community adopt and experiment with it so enthusiastically! 🥳 https://x.com/soyposmoderno/status/2077806222980649300/video/1
