X3D Reference

MotorJoint

MotorJoint

MotorJoint drives relative angular velocities between body1 and body2 within a common reference frame. Contains two RigidBody nodes (containerField values body1, body2).

The MotorJoint node belongs to the RigidBodyPhysics component and its container field is joints. It is available since X3D version 3.2 or later.

Hierarchy

Fields

SFNode [in, out] metadata NULL [X3DMetadataObject]

Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.

SFNode [in, out] body1 NULL [RigidBody]

Input/Output field body1.

SFNode [in, out] body2 NULL [RigidBody]

Input/Output field body2.

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.

SFFloat [in, out] axis1Angle [-π,π]

Axis1Angle (radians) is rotation angle for corresponding motor axis when in user-calculated mode.

SFFloat [in, out] axis1Torque (-∞,∞)

Axis1Torque is rotational torque applied by corresponding motor axis when in user-calculated mode.

SFFloat [in, out] axis2Angle [-π,π]

Axis2Angle (radians) is rotation angle for corresponding motor axis when in user-calculated mode.

SFFloat [in, out] axis2Torque (-∞,∞)

Axis2Torque is rotational torque applied by corresponding motor axis when in user-calculated mode.

SFFloat [in, out] axis3Angle [-π,π]

Axis3Angle (radians) is rotation angle for corresponding motor axis when in user-calculated mode.

SFFloat [in, out] axis3Torque (-∞,∞)

Axis3Torque is rotational torque applied by corresponding motor axis when in user-calculated mode.

SFInt32 [in, out] enabledAxes 1 [0,3]

EnabledAxes indicates which motor axes are active. (0) none, (1) axis 1, (2) axes 1 and 2, (3) all three axes.

SFVec3f [in, out] motor1Axis 0 0 0

Motor1Axis defines axis vector of corresponding motor axis.

Hint

0 0 0 means motor disabled.

SFVec3f [in, out] motor2Axis 0 0 0

Motor2Axis defines axis vector of corresponding motor axis.

Hint

0 0 0 means motor disabled.

SFVec3f [in, out] motor3Axis 0 0 0

Motor3Axis defines axis vector of corresponding motor axis.

Hint

0 0 0 means motor disabled.

SFFloat [in, out] stop1Bounce [0,1]

Hint

0 means no bounce, 1 means return velocity matches.

SFFloat [in, out] stop1ErrorCorrection 0.8 [0,1]

Stop1ErrorCorrection is fraction of error correction performed during time step once stop point is reached.

Hint

0 means no error correction, 1 means all error corrected in single step.

SFFloat [in, out] stop2Bounce [0,1]

Stop2Bounce is velocity factor for bounce back once stop point is reached.

Hint

0 means no bounce, 1 means return velocity matches.

SFFloat [in, out] stop2ErrorCorrection 0.8 [0,1]

Stop2ErrorCorrection is fraction of error correction performed during time step once stop point is reached.

Hint

0 means no error correction, 1 means all error corrected in single step.

SFFloat [in, out] stop3Bounce [0,1]

Stop3Bounce is velocity factor for bounce back once stop point is reached.

Hint

0 means no bounce, 1 means return velocity matches.

SFFloat [in, out] stop3ErrorCorrection 0.8 [0,1]

Stop3ErrorCorrection is fraction of error correction performed during time step once stop point is reached.

Hint

0 means no error correction, 1 means all error corrected in single step.

SFFloat [out] motor1Angle

Motor1Angle provides calculated angle of rotation (radians) for this motor joint from last frame.

SFFloat [out] motor3AngleRate

Motor3AngleRate provides calculated anglular rotation rate (radians/second) for this motor joint from last frame.

SFBool [ ] autoCalc FALSE

AutoCalc controls whether user manually provides individual angle rotations each frame (false) or if angle values are automatically calculated by motor implementations (true).
