panda3d.core.TrackerNode¶

from panda3d.core import TrackerNode

class TrackerNode¶

Bases: DataNode

This class reads the position and orientation information from a tracker device and makes it available as a transformation on the data graph. It is also the primary interface to a Tracker object associated with a ClientBase.

Inheritance diagram

__init__(client: ClientBase, device_name: str) → None¶

__init__(device: InputDevice) → None

__init__(param0: TrackerNode) → None

isValid() → bool¶: Returns true if the TrackerNode is valid and connected to a server, false otherwise.

getPos() → LPoint3¶

Returns the current position of the tracker, if it is available.

Return type: LPoint3

getOrient() → LOrientation¶

Returns the current orientation of the tracker, if it is available.

Return type: LOrientation

getTransform() → LMatrix4¶

Returns the current position and orientation of the tracker, as a combined matrix.

Return type: LMatrix4

getTime() → float¶: Returns the time of the tracker’s last update.

hasTime() → bool¶: True if this data comes with timestamps.

setTrackerCoordinateSystem(cs: CoordinateSystem) → None¶: Specifies the coordinate system that the tracker associated with this node will operate in. Normally, this is set from the ClientBase that’s used to create the TrackerNode, so it should not need to be set on an individual tracker basis.

getTrackerCoordinateSystem() → CoordinateSystem¶

Returns the coordinate system that the tracker associated with this node will operate in.

Return type: CoordinateSystem

setGraphCoordinateSystem(cs: CoordinateSystem) → None¶: Specifies the coordinate system that the TrackerNode will convert its transform into for passing down the data graph. Normally, this is CS_default.

getGraphCoordinateSystem() → CoordinateSystem¶

Returns the coordinate system that the TrackerNode will convert its transform into for passing down the data graph. Normally, this is CS_default.

Return type: CoordinateSystem

static getClassType() → TypeHandle¶

Return type: TypeHandle
