Member Function Documentation

◆ getCamera()

SoCamera * NbNavigationControl::getCamera ( void ) const

Returns the pointer the the camera that is to be manipulated.

See also: setCamera

◆ getSceneGraph()

SoNode * NbNavigationControl::getSceneGraph ( void ) const

Returns the set scene graph.

See also: setSceneGraph

◆ getUpVector()

const SbVec3f & NbNavigationControl::getUpVector ( void ) const

This method returns the up vector. Default value is (0, 0, 0) which is interpreted as no up direction.

See also: setUpVector, resetRoll

◆ getViewportAspect()

float NbNavigationControl::getViewportAspect ( void ) const

Returns the aspect ratio of the viewport - its width divided by height.

◆ getViewportSize()

SbVec2s NbNavigationControl::getViewportSize ( void ) const

Returns the size of the viewport in pixels.

◆ moveCamera() [1/2]

void NbNavigationControl::moveCamera ( const SbVec3f & distance ) const

This method moves the camera.

See also: reorientCamera, saveCamera, restoreCamera

◆ moveCamera() [2/2]

void NbNavigationControl::moveCamera	(	float	factor,
		const SbBool	keepfocalpoint = TRUE ) const

This camera moves the camera straight forwards towards the focal point. The position of the focal point can be kept, or moved equally forwards as well.

◆ pick()

SoPath * NbNavigationControl::pick	(	SbVec2s	pos,
		SbVec3d &	pickpos ) const

Performs a pick in the scene.

pos is the 2D location on the viewport. pickpos is the returned 3D pick position.

The method returns the SoPath to the picked object if a point was picked, and NULL otherwise.

◆ pitchCamera()

void NbNavigationControl::pitchCamera ( float angle ) const

This method reorients the camera in the pitch plane.

See also: rollCamera, yawCamera

◆ pointDir()

void NbNavigationControl::pointDir ( const SbVec3f & dir ) const

Orients the camera so that it points in the given direction.

See also: reorientCamera

◆ reorientCamera() [1/2]

void NbNavigationControl::reorientCamera ( const SbRotation & rot ) const

This method reorients the camera according to the given rotation.

See also: saveCamera, restoreCamera, moveCamera

◆ reorientCamera() [2/2]

void NbNavigationControl::reorientCamera ( const SbVec3f & pointat ) const

This method reorients the camera to point at the pointat location.

◆ resetRoll()

void NbNavigationControl::resetRoll ( void ) const

This method resets the roll of the camera. If no up vector has been set, this method does nothing.

See also: rollCamera, setUpVector, getUpVector

◆ restoreCamera()

void NbNavigationControl::restoreCamera ( void ) const

This method restores the camera back to its last set position, or its initial position if saveCamera() has not been used yet.

See also: saveCamera

◆ rollCamera()

void NbNavigationControl::rollCamera ( float angle ) const

This method reorients the camera in the roll plane.

See also: pitchCamera, yawCamera

◆ saveCamera()

void NbNavigationControl::saveCamera ( void ) const

This method saves the current camera position and orientation. You can later restore the camera back to this position by calling restoreCamera().

See also: restoreCamera

◆ setCamera()

void NbNavigationControl::setCamera ( SoCamera * camera )

Sets the pointer to the camera that is to be manipulated.

See also: getCamera

◆ setSceneGraph()

void NbNavigationControl::setSceneGraph ( SoNode * scenegraph )

Sets the scene graph. Needed for certain navigation modes that for instance perform picking.

See also: getSceneGraph

◆ setUpVector()

void NbNavigationControl::setUpVector ( const SbVec3f & up )

This method lets you set the up vector. Default value is (0, 0, 0) which means no up vector is set.

See also: getUpVector, resetRoll

◆ setViewport()

void NbNavigationControl::setViewport ( const SbViewportRegion & vp )

This method sets the viewport information.

◆ viewAll()

void NbNavigationControl::viewAll ( void ) const

Positions the camera so that the whole model gets in view.

◆ yawCamera()

void NbNavigationControl::yawCamera ( float angle ) const

This method reorients the camera in the yaw plane.
