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 details

◆ CameraConstraint()

CameraConstraint::CameraConstraint ( const Camera *const camera )

explicit

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

◆ ~CameraConstraint()

virtual qglviewer::CameraConstraint::~CameraConstraint ( )

inlinevirtual

Virtual destructor.

Empty.

Function details

◆ camera()

const Camera* qglviewer::CameraConstraint::camera ( ) const

inline

Returns the associated Camera.

Set using the CameraConstraint constructor.

◆ constrainRotation()

void CameraConstraint::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 qglviewer::AxisPlaneConstraint.

◆ constrainTranslation()

void CameraConstraint::constrainTranslation	(	Vec &	translation,
		Frame *const	frame
	)
