SyntaxThe SoTrackballManip type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SoTrackballManip | Constructor. |
Methods| Name | Description | |
|---|---|---|
| AffectsState | Returns true if a node has an effect on the state during traversal. |
| Callback | (Inherited from SoTransformManip.) |
| CombineLeft | Convenience function that combines the effects of another transformation node into the current transformation stored in this node. |
| CombineRight | Convenience function that combines the effects of another transformation node into the current transformation stored in this node. |
| 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 SoTransformManip.) |
| 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 SoTransformManip.) |
| GetDragger | Returns the dragger being used by this manipulator. |
| 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 SoTransformManip.) |
| GetName | Returns the name of an instance. |
| GetPrimitiveCount | (Inherited from SoTransform.) |
| GetRenderEngineMode | Returns the supported Render engine mode. |
| GetRenderUnitID | (Inherited from SoNode.) |
| GetRotationSpaceMatrix | Returns composite matrix that transforms from object space to rotation space (the space after the scale and rotation). |
| GetScaleSpaceMatrix | Returns composite matrix that transforms from object space to scale space (the space after the scale). |
| GetStringName | (Inherited from SoBase.) |
| GetTranslationSpaceMatrix | Returns composite matrix that transforms from object space to translation space (the space after scale, rotation, and translation). |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GLRender | (Inherited from SoTransformManip.) |
| GLRenderBelowPath | (Inherited from SoNode.) |
| GLRenderInPath | (Inherited from SoNode.) |
| GLRenderOffPath | (Inherited from SoNode.) |
| GrabEventsCleanup | (Inherited from SoNode.) |
| GrabEventsSetup | (Inherited from SoNode.) |
| HandleEvent | (Inherited from SoTransformManip.) |
| 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. |
| MultLeft | Convenience function that combines the effects of a matrix transformation into the current transformation stored in this node. |
| MultRight | Convenience function that combines the effects of a matrix transformation into the current transformation stored in this node. |
| Pick | (Inherited from SoTransformManip.) |
| PointAt | Sets the node to translate the origin to the fromPoint and rotate the negative z-axis (0,0,-1) to lie on the vector from fromPoint to toPoint . |
| RayPick | (Inherited from SoNode.) |
| Recenter | Changes the center of the transformation to the given point without affecting the overall effect of the transformation. |
| ReplaceManip | Replaces the tail of the path, which must be this manipulator, with the given OIV.Inventor.Nodes.SoTransform node. |
| ReplaceNode | Replaces the tail of the path with this manipulator. |
| Search | (Inherited from SoTransformManip.) |
| 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. |
| SetMatrix | Sets the fields in the node to implement the transformation represented by the given matrix. |
| 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 SoTransformManip.) |
Properties| Name | Description | |
|---|---|---|
 | center | Origin for scale and rotation. |
| IsDisposable | ISafeDisposable interface implementation.
(Inherited from SoDisposable.) |
| rotation | Rotation specification. |
| scaleFactor | Scale factors. |
| scaleOrientation | Rotational orientation for scale. |

| UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) |
RemarksOIV.Inventor.Manips.SoTrackballManip is derived from OIV.Inventor.Nodes.SoTransform (by way of OIV.Inventor.Manips.SoTransformManip). When its fields change, nodes following it in the scene graph rotate, scale, and/or translate.
As a subclass of OIV.Inventor.Manips.SoTransformManip, this manipulator also has a 3D interface to edit some of its fields. In this case, the interface edits the rotation and scaleFactor fields.
A manipulator differs from a dragger. When you move a dragger, no other nodes are affected. When you move an OIV.Inventor.Manips.SoTransformManip, other nodes move along with it. (See the reference page for OIV.Inventor.Manips.SoTransformManip).
The interface for an OIV.Inventor.Manips.SoTrackballManip is exactly the same as that of the OIV.Inventor.Draggers.SoTrackballDragger. To find out more about the interface, see the reference page for OIV.Inventor.Draggers.SoTrackballDragger. To find out how the manipulator uses a dragger to provide its interface, see the reference page for OIV.Inventor.Manips.SoTransformManip.
On screen, this manipulator will surround the objects influenced by its motion. This is because it turns on the surroundScale part of the dragger (See the reference page for OIV.Inventor.Nodes.SoSurroundScale)
