Navigator Tree Nodes
The tree displayed in the Navigator window has nodes of many different types. Nodes can represent 1) a single object in the model or associated with the model or 2) collections of objects (for example, the node corresponding to the set of rigid bodies in a model). Nodes that correspond to multiple objects have a folder-like representation in the navigator tree.
The following table describes the types of objects that can be represented in the tree and their corresponding icons. Some objects, such as markers, are not represented in the tree in order to present a less cluttered view when dealing with large models.
Node Label | Icon | What the node represents |
[Model Name] | A full OpenSim model | |
| The set of rigid bodies in the model | |
| A single rigid body | |
| A single muscle wrap object | |
| The set of geometry files for a body | |
| A geometry (.vtp) Ayman, does this have to be a .vtp file?file with editable display properties | |
Forces | All forces in the model | |
| All Muscles | |
| A muscle group | |
| A single muscle | |
| All non-muscle actuators | |
| A torque | |
| A Generalized force | |
| A force | |
| A force | |
Joints | All joints in the model | |
| A single joint | |
| All degrees of freedom for a joint | |
| A function describing dof changes | |
Constraints | A list of constraints associated with the model | |
| A specific constraint | |
Contact Geometry | A list of contact geometry associated with the model | |
Markers | A list of markers associated with the model | |
| A specific marker | |
Motions | All motions associated with a model | |
| A specific motion |
Key Bindings
Selection of nodes in the Navigator tree follows the standard conventions:
- Select objects by clicking the left mouse button once on the tree node
- Select a region of contiguous nodes in the tree using shift+left mouse
- Clicking the left mouse button on a node that has already been selected causes it to be deselected
- Add objects to a group of selected objects by using ctrl+left mouse
In addition, clicking the left mouse button twice (double clicking) a node toggles the display of its corresponding object. This is useful when quickly navigating the model to investigate where different objects are in the 3D View window.
