SyntaxThe SoTracker type exposes the following members.
ConstructorsMethods| Name | Description | |
|---|---|---|
 | AffectsState | Returns true if a node has an effect on the state during traversal. |
| Callback | (Inherited from SoNode.) |
| Copy | Calls Copy(false). (Inherited from SoNode.) |
| Copy(Boolean) | Creates and returns an exact copy of the node. |
| CopyFieldValues(SoFieldContainer) | Calls CopyFieldValues(fc, false). (Inherited from SoFieldContainer.) |
| CopyFieldValues(SoFieldContainer, Boolean) | Copies the contents of fc's fields into this object's fields. |
| Dispose |
Releases all resources used by SoDisposable.
(Inherited from SoDisposable.) |
| Distribute | (Inherited from SoNode.) |
| DoAction | (Inherited from SoNode.) |
| EnableNotify | Notification at this Field Container is enabled (if flag == true) or disabled (if flag == false). |
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| FieldsAreEqual | Returns true if this object's fields are exactly equal to fc's fields. |
| Get | Returns the values of the fields of this object in the Open Inventor ASCII file format in the given string. |
| GetAllFields | Returns a list of fields, including the eventIn's and eventOut's. |
| GetAlternateRep | This method is called by actions to allow the node to provide an "alternate representation" when appropriate (typically depending on the action type). |
| GetBoundingBox | (Inherited from SoNode.) |
| GetControllerReader | Gets associated controller reader. |
| GetEventIn | Returns a the eventIn with the given name. |
| GetEventOut | Returns the eventOut with the given name. |
| GetField | Returns a the field of this object whose name is fieldName. |
| GetFieldName | Returns the name of the given field in the fieldName argument. |
| GetFields | Appends references to all of this object's fields to resultList, and returns the number of fields appended. |
| GetHashCode |
Overrides GetHashCode().
(Inherited from SoNetBase.) |
| GetMatrix | (Inherited from SoNode.) |
| GetName | Returns the name of an instance. |
| GetPrimitiveCount | (Inherited from SoNode.) |
| GetRenderUnitID | (Inherited from SoNode.) |
| GetStringName | (Inherited from SoBase.) |
| GetTrackerReader | Gets associated tracker reader. |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GLRender | (Inherited from SoNode.) |
| GLRenderBelowPath | (Inherited from SoNode.) |
| GLRenderInPath | (Inherited from SoNode.) |
| GLRenderOffPath | (Inherited from SoNode.) |
| GrabEventsCleanup | (Inherited from SoNode.) |
| GrabEventsSetup | (Inherited from SoNode.) |
| HandleEvent | (Inherited from SoNode.) |
| HasDefaultValues | Returns true if all of the object's fields have their default values. |
| IsBoundingBoxIgnoring | This method is used by getBoundingBox action traversal to know if the current node must be traversed or not, ie the bounding should be ignored. |
| IsNotifyEnabled | Notification is the process of telling interested objects that this object has changed. |
| IsOverride | Returns the state of the override flag. |
| IsSynchronizable | Gets the ScaleViz synchronizable state of this object. |
| Pick | (Inherited from SoNode.) |
| RayPick | (Inherited from SoNode.) |
| Search | (Inherited from SoNode.) |
| Set | Sets one or more fields in this object to the values specified in the given string, which should be a string in the Open Inventor file format. |
| SetName | (Inherited from SoBase.) |
| SetOverride | Turns the override flag on or off. |
| SetSynchronizable | Sets this to be a ScaleViz synchronizable object. |
| SetToDefaults | Sets all fields in this object to their default values. |
| ToString |
Converts this SoBase structure to a human readable string.
(Inherited from SoBase.) |
| Touch | Marks an instance as modified, simulating a change to it. |
| Write | (Inherited from SoNode.) |
Properties| Name | Description | |
|---|---|---|
 | calibrate | Optional calibration matrix that converts from actual tracker coordinates to world coordinates. |
| defaultCameraPosition | Initial camera position. |
| defaultObjectBoxMaxDim | Radius of a bounding sphere. |
| defaultObjectPosition | Initial scene position. |
| headTrackerId | ID of the trackd sensor which should be used to control the head/camera. |
| interEyeDistance | Inter-eye distance with respect to the system coordinates. |
| IsDisposable | ISafeDisposable interface implementation.
(Inherited from SoDisposable.) |
| server | Specifies a string used to initialize the connection to the tracking system. |
| unitScaleFactor | A factor that will be applied to all position coordinates retrieved from the tracking system. |
| UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) |
| wandFile | Name of a geometry file that the MultiPipe viewer uses for the wand geometry. |
| wandTrackerId | ID of the trackd sensor which should be used to control the wand. |
RemarksThe SoTracker class is used in ScaleViz configuration file to set various parameters for an immersive, tracked environment. Some of these parameters set objects within the scene graph. The camera position is set initially to defaultCameraPosition. A transform node is inserted in the scene graph after the camera node. This transform node contains the defaultObjectPosition as well as the scaling (computed with) others set tracker information (trackd shared memory keys, head/wand ids...).
