This page provides instructions on how to use the 6-Rigid Body skeleton markerset for full-body skeleton tracking.
The 6 Rigid Body skeleton feature is not exposed in Motive 2.0. To access this skeleton template, please contact our support.
The 6 Rigidbody Skeleton markerset allows users to use just rigid bodies to establish full body skeleton tracking. A total of six rigid bodies are attached at specific locations of the subject and Motive solves the entire skeleton through inverse kinematics. The rigid bodies are attached to the head, left-hand, right-hand, hip, left-foot, and right-foot, and then the pivot point of those rigid bodies needs be translated over to the corresponding joints.
Step 1) Prepare 6 rigid bodies with markers.
Step 2) Attach rigid bodies at the following locations:
Step 3) Make sure the rigid bodies are securely attached.
Step 1) First of all, define rigid body assets for all of the attached rigid bodies.
Step 2) Name the rigid bodies "Head", "Hip", "LHand", "RHand", "LFoot", and "RFoot".
Step 3) Position the rigid body pivot points. Use the Gizmo tool and move the rigid body pivot points so that each pivot point is located at its parent joint axis. Refer to the image below.
Step 4) Orient the rigid body pivot points so that all of its z-axis is facing in forward-direction.
Step 5) The rigid body pivot point should be positioned and oriented something like the image below (Grayscale image).
Step 6) Open the Skeleton pane and select the 6 Rigid Body Skeleton markerset.
Step 7) Select all six rigid bodies and press "Create" on the Skeleton pane.
