(1) Create a Markerset (rigid body)

XINGYING software supports the creation of Markerset in real time, which requires that objects with reflective markers are placed in the site, and each reflective marker can be seen in the 3D view of the software (see Figure 47).

Figure 47

After confirming that the software is in the playing state, click the "Freeze Frame" button at the top of the software interface to freeze the 3D view (as shown in Figure 48). After successfully freezing, the button will display "Release freeze" (as shown in Figure 49);

You can use the following methods to select a reflective marker in the 3D view: Hold down the Shift key, hold down the left mouse button and drag the box to select the reflective marker to create a rigid body. You can also hold down Ctrl or Shift and use the left mouse button to select the reflective marking points that need to be created with rigid bodies one by one. Select multiple reflective marking points attached to the surface of the rigid body in the 3D view with the mouse. One rigid body needs at least 3 reflective marking points (as shown in Figure 50).

After selecting three or more points, right-click and select Create Rig. In the pop-up window, you can customize the name of the created rigid body (Figure 51). No rigid body with the same name is allowed in the software. If the name of the custom rigid body is the same, the Create button is gray and cannot be clicked. When duplicate rigid body names appear, you need to manually delete the.mars file with duplicate names from the working directory. The working path contains a rigid body name with a discontinuous serial number. By default, the software generates a rigid body name with a lower serial number. Without modifying the rigid body name, the rigid body name defaults to "Tracker0, 1, 2..... "Increasing. The points will form a Markerset, the reflective points will be named and connected, and a rigid body will be created in the positive direction of the Y-axis (Figure 52);

The maximum number of rigid bodies created is 100. When a rigid body is created to 101, the software will pop up to prompt (Figure 53);

Click the "Unfreeze" button to release the frozen state of the 3D view. When moving the captured object, you can see that Markerset will follow the activity of the captured object in real time, and you can also directly collect data in this state.
