How to transform my mesh data into the network topology structure required by OSSO, where Vertices=6890? #13

Dear Marilyn Keller,

I would like to obtain the internal skeletal structure of my surface data. My mesh data has Vertices=10127706, which does not meet the required vertex count for STAR. How can I modify it? Could you please guide me?

Kind regards, Huan Yin

Dear Huan, thanks for using Osso. Fist you need to align the SMPL model to your mesh. We do not release this code but you can look over there:https://github.com/bharat-b7/RVH_Mesh_RegistrationOr use meshcapade service but it's not free:https://me.meshcapade.com/from-scansThat will give you a SMPL mesh that has the same shape and pose as your mesh but has the topology requested to run the OSSO inference and get the skeleton.I hope this helps.Best, Marilyn

To add more details for anyone stuck by this. To align SMPL to a scan, you can use the smplx package and pytorch. Use pytorch to optimize SMPL's shape (beta) and pose (theta) to minimize the distance between the SMPL mesh and your scan's mesh.
