Helen Hayes models with 29, 26, and 19 points created in real-time have virtual marker points built into the templates.
After loading Helen Hayes model data in post-processing mode, open the VMarker chart. In the "Virtual Markers" tab of the asset panel, select the VMarker points of the template. The selected VMarker points' X, Y, Z coordinates and their maximum and minimum values (11.6.1) will be displayed on the chart. The cross markers on the joints of the Helen Hayes body in the 3D view are the built-in VMarker points of the template.
To create virtual marker points, named points must exist in the template. We can record a set of data with rigid bodies in real-time mode or manually create a rigid body in post-processing mode, then bind virtual marker points to each named point on the rigid body.
First, select the rigid body template for which you want to create a VMarker in the asset panel, then select the "Virtual Markers" tab and create the name for the virtual marker point (11.6.2).
Select the VMarker point from the list, and in the advanced properties below, set the properties of the virtual marker point (11.6.3):
Choose the default type "Three-Point (Value)".
Virtual marker points do not need to set binding points.
Double-click "Origin, Long Axis, Plane Points" to select named points. Once set, the initial position of the VMarker point will be displayed at the origin.
Enter the offset values in the X, Y, Z offset input fields. The position of the created VMarker point will be shifted according to the offset values. If no offset values are set, the VMarker point will be displayed at the origin position.
Follow the above steps to set properties for other created virtual marker points. Click the save button in the asset list to save the virtual marker points created this time.
Open the VMarker chart, select our created virtual marker points, and the waveform of the virtual marker points, along with their XYZ coordinates and maximum and minimum values, will be displayed on the chart.
Click on the file in the upper left corner -- save motion capture data. After switching to real-time mode, load the rigid body asset with virtual marker points and click play. Once the rigid body is recognized, the virtual marker points will be displayed in the 3D view.
