BallJoint
Overview
BallJoint represents an unconstrained joint between two bodies that pivot about a common anchor point. Contains two RigidBody nodes (containerField values body1, body2).
The BallJoint node belongs to the RigidBodyPhysics component and requires at least level 2, its default container field is joints. It is available from X3D version 3.2 or higher.

Fields
SFNode [in, out] metadata NULL [X3DMetadataObject]
Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.
Hint
MFString [in, out] forceOutput “NONE” [“ALL”, “NONE”, …]
forceOutput controls which output fields are generated for the next frame. Values are ALL, NONE, or exact names of output fields updated at start of next frame.
SFVec3f [in, out] anchorPoint 0 0 0 (-∞,∞)
anchorPoint is joint center, specified in world coordinates.
SFVec3f [out] body1AnchorPoint
body1AnchorPoint describes anchorPoint position relative to local coordinate reference frame.
Hint
- Can detect separation if body1AnchorPoint!=body2AnchorPoint.
Warning
- It is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
SFVec3f [out] body2AnchorPoint
body2AnchorPoint describes anchorPoint position relative to local coordinate reference frame.
Hint
- Can detect separation if body1AnchorPoint!=body2AnchorPoint.
Warning
- It is an error to define this transient outputOnly field in an X3D file, instead only use it a source for ROUTE events.
SFNode [in, out] body1 NULL [RigidBody]
The body1 and body2 fields indicate the two RigidBody nodes connected by this joint.
SFNode [in, out] body2 NULL [RigidBody]
The body1 and body2 fields indicate the two RigidBody nodes connected by this joint.
Advice
Hint
- RigidBodyPhysics component, level 2.
