This Operation is used to create a set of corresponding point pairs. The resulting outputs may be used directly by Topo Transfer as landmark constraints as well as in other SOP networks. For ease of manipulation in downsteam SOP networks the corresponding point pairs are separated into two outputs with a common string attribute to identify the associations.
Creating landmark data in the view state
Generate new landmarks
Create landmarks from initial source point data
Create landmark correspondence between given source and target point data
To delete landmarks
To supply the Topo Landmark output as landmarks for the Topo Transfer node.
For more information about using Topo Landmark with Topo Transfer, see the help page for Topo Transfer.
When in the Topo Landmark view state, a toolbar appears across the top of the viewport. This toolbar contains the controls that allow you to create and edit landmarks.
Switches between different interactive modes. The options include:
Allows creating and editing of landmark pairs.
In this mode, landmarks correspondences are established when unstructured source and target points are provided as optional inputs.
This mode allows landmark pairs to be unbound.
Controls which types of landmarks to display.
Displays the landmarks relevent to all modes.
Displays only the landmarks relevent to the current mode.
Controls how landmarks labels should be displayed.
No labels are displayed.
Displays the label for each landmark pair.
Displays only an index number as the lable.
A string field where the label prefix can be specified.
Switches which landmark guide mesh—source or target—is shown in the viewport.
You can also use the hotkey G to toggle between displaying the source or target guide meshes.
Displays the source landmark guide mesh in the viewport.
Displays the target landmark guide mesh in the viewport.
Show Source Silhouette
When on, displays a transparent version of the source landmark guide mesh when you are viewing the target landmark guide mesh.
Show Geometry Colors
When on, displays either the geometry colors or texture data on the source and target guide mesh. This feature is useful when placing landmarks relative to annotations in the scan data.
Discards all landmarking done in the view state, and reinitializes the view state from the node input data.
The name given to the string attribute on the outputs that will contain the labels.
A string prefix used before each identification number in the label names.
The source reference geometry on which source points are located.
When used with Topo Transfer, the source geometry used here does not need to be the same as the source geometry used in the Topo Transfer node.
The target reference geometry on which the corresponding target points are located.
When used with Topo Transfer, the target geometry used here does not need to be the same as the target geometry used in the Topo Transfer node.
Optional source points to be used when editing the set of correspondence pairs.
The source points may be either labeled or unlabeled.
Optional target points to be used when editing the set of correspondence pairs.
The target points may be either labeled or unlabeled.
