When rotationConstraintType() is AxisPlaneConstraint::AXIS, constrain rotation to be a rotation around an axis whose direction is defined in the Frame local coordinate system by rotationConstraintDirection(). | |

Depending on translationConstraintType(), constrain translation to be along an axis or limited to a plane defined in the Frame local coordinate system by translationConstraintDirection(). | |
Detailed Description
An AxisPlaneConstraint defined in the Frame local coordinate system.
The translationConstraintDirection() and rotationConstraintDirection() are expressed in the Frame local coordinate system (see Frame::referenceFrame()).
See the constrainedFrame example for an illustration.
