## Detailed Description

An AxisPlaneConstraint defined in the world coordinate system.

The translationConstraintDirection() and rotationConstraintDirection() are expressed in world coordinate system.

See the constrainedFrame and multiView examples for an illustration.

## Constructor & Destructor Documentation

| virtual

Virtual destructor. Empty.

## Member Function Documentation

void constrainRotation | ( | Quaternion & | rotation,
|  | Frame *const | frame
| ) |  |
| virtual

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

Reimplemented from AxisPlaneConstraint.

void constrainTranslation | ( | Vec & | translation,
|  | Frame *const | frame
| ) |  |
| virtual

Depending on translationConstraintType(), constrain `translation` to be along an axis or limited to a plane defined in the world coordinate system by translationConstraintDirection().

Reimplemented from AxisPlaneConstraint.
