SceneExaminer Class |
The SceneExaminer is an extension of the SceneInteractor node that allows providing the camera and headlight manipulations like panning, zooming and orbiting similar to the behavior of the classic Open Inventor viewer classes SoWinExaminerViewer (NavigationModes Orbit) and SoWinPlaneViewer (NavigationModes Plane). Similar behavior includes a 'headlight', i.e. an SoDirectionalLight node automatically aligned with the camera's view direction.
Namespace: OIV.Inventor.ViewerComponents.Nodes
The SceneExaminer type exposes the following members.
Name | Description | |
---|---|---|
SceneExaminer |
Default constructor.
|
Name | Description | |
---|---|---|
AddChild | Adds a child as last one in group. | |
AdjustClippingPlanes |
Adjust near and far clipping planes to minimize clipping of objects in the
scene. This adjustment, based on the bounding box of the scene, ensures
that shapes will not be clipped and also that depth buffer precision is
maximized. This method should be called before each render traversal.
(Inherited from SceneInteractor.) | |
AffectsState | Returns true if a node has an effect on the state during traversal. | |
Callback | (Inherited from SoSeparator.) | |
ClearCacheList | (Inherited from SoSeparator.) | |
Copy | Calls Copy(false). (Inherited from SoNode.) | |
Copy(Boolean) | Creates and returns an exact copy of the node. | |

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.) | |

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). | |

InsertChild | Adds a child so that it becomes the one with the given index. | |
IsBoundingBoxIgnoring | Used by BoundingBoxAction to known if bounding box computation should be ignored or not. | |
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 SoGroup.) | |
RayPick | (Inherited from SoSeparator.) | |

keeping the "up" direction of the camera parallel to the specified up
vector.

The SceneExaminer is not directly comparable with a classic Open Inventor viewer as it does not provide any GUI (no buttons, no popup menu) and fewer interactive features (no animation). However it does provide a touch event handler that allows manipulating a scene on a touch device. See parent class SceneInteractor for more details about the structure of the internal scene graph.
The SceneExaminer uses an instance of SoCameraInteractor in order to manipulate the camera in response to OpenInventor events.
