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
SFVec3f centerOfRotation SFVec3f inputOutput 0 0 0 centerOfRotation point relates to NavigationInfo EXAMINE mode.
SFRotation 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.
SFVec3f position SFVec3f inputOutput 0 0 10 Position (x, y, z in meters) relative to local coordinate system.
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 isInteractive SFBool outputOnly FALSE Event true sent when node becomes interactive, user can navigate the view transformation
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
SFTime bindTime SFTime outputOnly Event sent when node becomes active/inactive.
SFBool isBound SFBool outputOnly FALSE Event true sent when node becomes active, event false sent when unbound by another node.
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)
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
