Viewfrustum

The Viewfrustum node allows to define a camera position and projection utilizing a standard OpenGL projection/modelview pair

Filter: X3D only | Avalon only | All
id Name DataType PartType Default ValueType Description
MFNode children MFNode inputOutput the children fields allow to place object relative to the current camera transformation.
MFNode effects MFNode inputOutput VisualEffects Specifies the desired global effects like depth of field and motion blur for the post-processing step that are specific to a certain camera or lens type.
MFNode navigator MFNode inputOutput Navigator3D holds the 3d navigator which will be called for bound nodes
MFString logFeature MFString inputOutput state, child, parent, route, eventIn, eventOut controls the logging of changes, state: log state changes (e.g. live), child: log child add/remove, parent: log parent add/remove, route: log route add/remove; eventIn: log receiving of events, eventOut: log sending of events: guiView, runtime system should create node-view, guiEdit: runtime system should create node-editeverything: log everything
SFBool isBound SFBool outputOnly FALSE Event true sent when node becomes active, event false sent when unbound by another node.
SFBool isDefault SFBool initializeOnly FALSE indicates if the object is the default bindable or not (generated if the scene did not contain any Bindable of a missing Type (e.g. Viewpoint))
SFBool isInteractive SFBool outputOnly FALSE Event true sent when node becomes interactive, user can navigate the view transformation
SFBool jump SFBool inputOutput TRUE Sspecifies whether the user's view jumps to the position and orientation of a bound node or remains unchanged
SFBool retainUserOffsets SFBool inputOutput FALSE retainUserOffsets is FALSE, the viewer is returned to the originally defined viewpoint position/orientation after local navigation
SFBool set_bind SFBool inputOnly Sending event set_bind=true makes this node active. Sending event set_bind=false makes this node inactive. Thus setting set_bind to true/false will pop/push (enable/disable) this Bindable
SFFloat zFar SFFloat inputOutput -1 z-far position; used for clipping
SFFloat zNear SFFloat inputOutput -1 z-near position; used for clipping
SFMatrix4f modelview SFMatrix4f inputOutput identity camera modelview matrix
SFMatrix4f projection SFMatrix4f inputOutput identity camera projection matrix
SFMatrix4f transformation_request SFMatrix4f outputOnly sends a new request to evaluate a local transformation. Its mainly used together with a NavigationEvaluator node to verify the transformation given by the navigator
SFMatrix4f transformation_result SFMatrix4f inputOnly this slot is used to transform the view to the given local transformation. It is mainly used to return the camera transformation after processed by a NavigationEvaluator
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
SFNode splitGroup SFNode inputOutput SplitGroup holds SplitGroup node for this bindable
SFString description SFString initializeOnly Text description or navigation hint to be displayed for this Bindable. Hint: make descriptions clear and readable. Warning: without description, Bindable (e.g. Viewpoint objs) can not be activated/deactivated with keyboard or gui messages (e.g. switched with PgUp bzw PgDn)
SFString triggerName SFString initializeOnly Synchronize name of the dynamic context-slot which is used by the run-time environment (e.g. Jobs) to trigger the node. Life-Nodes will automatically connect the context-eventOutut to the triggerSlot-eventInput Slot.
SFTime bindTime SFTime outputOnly Event sent when node becomes active/inactive.
SFTime triggerSlot SFTime inputOnly slot which is used internally to connect a dynamic context-slot which name is set by the triggerName value. Its used automatically to install run-time environment trigger.
XFAny bind XFAny inputOnly sending any event to this slot will bind/activate the Bindable
