How to get kinematic_chain and raw_offsets?

Open hdjsjyl opened this issue 2 years ago • 2 comments

Hi Author, As a novice for 3D motion, I would like to ask a (stupid maybe) question, how to get kinematic_chain and raw_offsets? Any advice would be appreciated, thank you!

Hi,

Usually if you are working on mocap data, e.g., bvh, the data will provide you the offset and kinematic chain. The kinematic chain basically defines the chain of forward kinematics. In our case, we came up with a skeleton, which is also the simplest case. There is no absolute offset. You could roughly define a raw_offset, and it should works as long as you stick the same raw_offset all the time.

Hi @EricGuo5513 , Really appreciate your reply. Do you have some suggestions for learning 3D motion to understand the basic definitions in 3D motion data, 3D data rendering, etc? Thank you
