the src.bvh and dst.bvh must be the same Skeletal hierarchy ?

[luoww1992]

Q1, the src.bvh and dst.bvh must be the same Skeletal hierarchy ?
or main body skeletons are the same Skeletal hierarchy ?
if i use smpl_24, kinectv2_25, h36m_17, h36m_25, mpi_inf_3dhp_17, mpi_inf_3dhp_28, coco_19, smplx_42, ghum_35, lsp_14, sailvos_26, gpa_34, aspset_17, bml_movi_87, mads_19, berkeley_mhad_43, total_capture_21, jta_22, ikea_asm_17, human4d_32, 3dpeople_29...
these are {dataset}_{joint_numbers}
if main body skeleton have same Skeletal hierarchy, we can use it to retarget skeleton ?

Q2, i have see how to make motion data by the input.bvh, is it get 3d skeleton world position by bvh file by func: BVH_file(file).to _terson() ? which things the func does ?
