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

◆ ~WorldConstraint()

virtual ~WorldConstraint ( )

Virtual destructor. Empty.

Member Function Documentation

◆ constrainRotation()

void constrainRotation ( Quaternion rotation,
Frame *const  frame 

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.

◆ constrainTranslation()

void constrainTranslation ( Vec translation,
Frame *const  frame 

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.
