Custom data preprocessing #3

Open kai-lan opened 1 month ago

Hi,

Is it possible to preprocess custom data without Unity? It would be nice to be able to do it in a Python script.

Hi Kai-Lan,

Thanks for your question. It would be possible to imitate the Unity functions in python. However, it would require a decent amount of work and we don't have a plan to implement it for

Thank you for your reply. Can you tell me what it is done during data preprocessing? Is it simply conversion from a BVH file to a binary format? Otherwise, what extra properties are calculated?

The most important thing is to calculate the root coordinate, and covert joint rotations, velocities and positions in the root coordinate and export them for training.
