====== Data Tree Summary  ======

|{{:V3D_DataTree.png}}  |  |

In Visual3D, you can see the Data Tree by going to the Signals and Events tab.

Signals in Visual3D are referenced by how they are presented in the Data Tree:

  * Signal Type (Top level)
  * Signal Folder
  * Signal Name

There are only specific signal types that are allowed:

  * Event_Label
  * Target
  * Analog
  * Force
  * COFP
  * Freemoment
  * Landmark
  * Link_Model_Based
  * Kinetic_Kinematic
  * Derived
  * Metric
  * Frame_Numbers
  * Header Information
  * Parameters

In [[Visual3D:Documentation:Pipeline:Expressions:Expressions_Overview|Expressions]], signals are referenced using the following syntax:

  * SignalType::SignalFolder::SignalName
  * SignalType::SignalFolder::SignalName::Component

More information about the data tree can be found [[Visual3D:Documentation:Visual3D_Signal_Types:Data_Tree|here]].
