Filter: X3D only | Avalon only | All
id | Name | DataType | PartType | Default | ValueType | Description |
---|---|---|---|---|---|---|
children | MFNode | inputOutput | the children fields allow to place object relative to the current camera transformation. | |||
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. | ||
navigator | MFNode | inputOutput | Navigator3D | holds the 3d navigator which will be called for bound nodes | ||
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 | ||
isBound | SFBool | outputOnly | FALSE | Event true sent when node becomes active, event false sent when unbound by another node. | ||
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)) | ||
isInteractive | SFBool | outputOnly | FALSE | Event true sent when node becomes interactive, user can navigate the view transformation | ||
jump | SFBool | inputOutput | TRUE | Sspecifies whether the user's view jumps to the position and orientation of a bound node or remains unchanged | ||
retainUserOffsets | SFBool | inputOutput | FALSE | retainUserOffsets is FALSE, the viewer is returned to the originally defined viewpoint position/orientation after local navigation | ||
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 | |||
zFar | SFFloat | inputOutput | -1 | z-far position; used for clipping | ||
zNear | SFFloat | inputOutput | -1 | z-near position; used for clipping | ||
modelview | SFMatrix4f | inputOutput | identity | camera modelview matrix | ||
projection | SFMatrix4f | inputOutput | identity | camera projection matrix | ||
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 | |||
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 | |||
metadata | SFNode | inputOutput | MetadataObject | container for payload metadata inside MetadataSet element | ||
splitGroup | SFNode | inputOutput | SplitGroup | holds SplitGroup node for this bindable | ||
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) | |||
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. | ||
bindTime | SFTime | outputOnly | Event sent when node becomes active/inactive. | |||
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. | |||
bind | XFAny | inputOnly | sending any event to this slot will bind/activate the Bindable |
