Viewpoint (Standard name: ViewBindable) (alias: PerspectiveViewpointBase)
Abstract Viewpoint provides a specific location and direction where the user may view the scene. Background, Fog, NavigationInfo, TextureBackground and Viewpoint are bindable nodes.

Filter: X3D only | Avalon only | All
id | Name | DataType | PartType | Default | ValueType | Description |
---|---|---|---|---|---|---|
centerOfRotation | SFVec3f | inputOutput | 0 0 0 | centerOfRotation point relates to NavigationInfo EXAMINE mode. | ||
orientation | SFRotation | inputOutput | 0 0 1 0 | Rotation (axis, angle in radians) of Viewpoint, relative to default -Z axis direction in local coordinate system. Hint: this is orientation _change_ from default direction (0 0 -1). Hint: complex rotations can be accomplished axis-by-axis using parent Transforms. | ||
position | SFVec3f | inputOutput | 0 0 10 | Position (x, y, z in meters) relative to local coordinate system. | ||
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 | ||
isInteractive | SFBool | outputOnly | FALSE | Event true sent when node becomes interactive, user can navigate the view transformation | ||
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 | |||
bindTime | SFTime | outputOnly | Event sent when node becomes active/inactive. | |||
isBound | SFBool | outputOnly | FALSE | Event true sent when node becomes active, event false sent when unbound by another node. | ||
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) | |||
metadata | SFNode | inputOutput | MetadataObject | container for payload metadata inside MetadataSet element |
