Rigid
InInputThe XINGYING software supports the creation of Markersets in Live, requiring objects with already attached reflective markers to be placed on the site, and each reflective marker point to be visible in the 3D view of the software；
Confirm that the software is in play, click the "Frozen" button at the bottom of the software interface to freeze the 3D view ；
There are the following methods for selecting reflective marker points in the 3D view: by holding down the Shift key while holding down the left mouse button and dragging the box selection, select the reflective marker points that need to create a rigid body to create the rigid body. You can also hold down the Ctrl or Shift keys and use the left mouse button to select the reflective marker points that need to be created for the rigid body one by one. Use the mouse to select multiple reflective marker points attached to the surface of the rigid body in the 3D view. A rigid body must have at least 3 reflective marker points . After selecting unnamed points in the freeze frame, the number of unnamed points in the frame will be displayed in Live in the lower left corner of the 3D view, The numbers in parentheses represent the number of boxed points, while the numbers to the left of parentheses represent the total number of Marker points in the 3D view；
After selecting three or more points, right-click and select Create Rig. In the pop-up window, you can customize and modify the name of the created rigid body. The software does not allow rigid bodies with the same name. If the custom rigid body name is duplicate, the "Create" button is grayed out and cannot be clicked. When duplicate rigid body names appear, you need to manually delete the. Mars file with the duplicate name from the working directory. Rigid body names with discontinuous serial numbers in the working path will be generated first by the software when creating rigid body names. If the rigid body name is not modified, it will default to incrementing from "Tracker0, 1, 2...". Multiple points will form a Market, and reflective identification points will be named and connected, while creating a rigid body in the positive Y-axis direction；
The maximum number of rigid bodies created is 100. When the 101st rigid body is created, the software will pop up a prompt；
Click on the "Freeze" button to unfreeze the 3D view. At this point, the active captured object can be seen, and the MarkerSet will follow the activity of the captured object in real time. In this state, data can also be directly collected；
Two points determine the orientation of the rigid body
Creating a rigid body can customize the orientation of the rigid body. The specific operation method is: after freezing, press the Ctrl key, and select the Marker point in the 3D view with the left mouse button. After successful creation, the orientation of the rigid body will be pointed from Marker1 to Marker2, which is to determine the orientation of the rigid body based on the first and second Marker points selected with the Ctrl key.
Change 6DOF of Rigid
After creating a rigid body, the skeleton of the rigid body can be displaced and rotated；
Click the freeze button, select the skeleton name of the rigid body in the asset, and click on the X/Y/Z axis offset below. You can see that a cross will appear in the center of the rigid body skeleton in the 3D view. Dragging an axis of the cross can achieve displacement of the skeleton, or you can click on the center point of the cross to drag the skeleton in any axis；
In the frozen frame state, skeleton can also be rotated. Click on the rotation axis X/Y/Z of the skeleton, and the center of the skeleton will display a rotating three-dimensional ring. Drag the ring to rotate the skeleton；
If you need to exit editing the displacement and rotation of skeleton, press Ctrl to exit the editing state, and the cross and circle will also disappear. After unfreezing, the displacement and rotation of skeleton will change in the 3D view.
