Collection of detected/tracked hands, where each hand is represented as a list of 21 hand landmarks in world coordinates. Each landmark is composed ofx,yandz: real-world 3D coordinates in meters with the origin at the hand’s approximate geometric center. MULTI_HANDEDNESS Collection of handed...
2) "pose_world_landmarks" field that contains the pose landmarks in real-world 3D coordinates that are in meters with the origin at the center between hips. 3) "left_hand_landmarks" field that contains the left-hand landmarks. 4) "right_hand_landmarks" field that contains the right...

The hand tracking main graph internally utilizes a hand detection subgraph, a hand landmark subgraph and a renderer subgraph. The subgraphs show up in the main graph visualization as nodes colored in purple, and the subgraph itself can also be visualized just like a regular graph. For more inf...
