tets_data.npz and neutral mesh #40

Open andrewhou1 opened 3 months ago

andrewhou1 commented 3 months ago

Thank you very much for releasing the code! I had a couple questions that I would appreciate if you could answer:

  1. Is the tets_data.npz file subject specific? Do we need to generate that for every subject separately? From my understanding it is the initialization of the neutral mesh points given the multi-view video capture, please correct me if this is not correct.
  2. Could you provide some more detail as to how you estimate the neutral mesh using SDF and multi-view videos? In particular, how do you separate the identity from the expressions? There was not a great amount of detail in the paper.
  3. If there's any additional code that you used to compute SDF or tets_data, could you please provide it or point me to code that I can use?

Thanks for your help and I look forward to your reply!
