Detailed Description

An AxisPlaneConstraint defined in the camera coordinate system.

The translationConstraintDirection() and rotationConstraintDirection() are expressed in the associated camera() coordinate system.

See the constrainedFrame and constrainedCamera examples for an illustration.

Constructor & Destructor Documentation

CameraConstraint (  const Camera *const   camera  )  [explicit]

Creates a CameraConstraint, whose constrained directions are defined in the camera coordinate system.

virtual ~CameraConstraint (   )  [virtual]

Virtual destructor. Empty.

---

Member Function Documentation

const Camera* camera (   )  const

Returns the associated Camera. Set using the CameraConstraint constructor.

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 camera() 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 camera() coordinate system by translationConstraintDirection(). Reimplemented from AxisPlaneConstraint.
