Properties
action
The trigger of the pointer action.
action
The type of the pointer action.
canvas
The canvas pointer coordinates in pixels.
nodeID
The current node ID of the pointer action depending on the expanded state of the node structure.
Note: The nodeID can be different from the targetNodeID depending on the expanded state of
the instance graph. The nodeID property stores the deepest clicked node ID webvis can find that
is not yet expanded whereas the targetNodeID property stores the leaf node ID at the current pointer
position.
normal
The 3D normal vector at the current pointer coordinates.
normalized
The normalized pointer coordinates between [0, 1].
position
The 3D position at the current pointer coordinates.
target
The target node ID of the pointer action.
Note: The targetNodeID can be different from the nodeID depending on the expanded state of
the instance graph. The targetNodeID property stores the leaf node ID at the current pointer
position whereas the nodeID property stores the deepest clicked node ID webvis can find that
is not yet expanded.
viewer
A reference to the related viewer.
Methods
request
- requestTopologyHandle(): Promise<TopologyHandle>
Returns the handle to the topological entity at the current pointer coordinates
Returns Promise<TopologyHandle>
Holds the information about a pointer action in the viewer.
An object of this type is propagated by all the events of the ViewerInteractionAPI interface.
