Question: Getting hand camera space coordinates in -xyz mode

[Moritz]

Hey,
I have a simple question regarding the -xyz mode: Am I correct in the assumption that one only gets the coordinate of the wrist in the camera space coordinate system and would have to manually calculate (not too difficult obviously) the camera space coordinates of the remaining landmarks?

Exactly.
Your suggestion of calculating the remaining landmarks coordinates is actually done in the 3D visulaization example: https://github.com/geaxgx/depthai_hand_tracker/tree/main/examples/3d_visualization in what I called "mixed" mode.
