Detailed Description

CameraView - is a Transform that is used to specify camera views from within the scene graph. The application must attach a camera to a CameraView via the NodePath from the top of the scene graph to the CameraView node itself, and accimulate the view matrix from this NodePath.

Member Function Documentation

virtual bool osg::CameraView::computeLocalToWorldMatrix	(	Matrix &	matrix,
		NodeVisitor *	nv
	)			const `[virtual]`

Reimplemented from osg::Transform.

virtual bool osg::CameraView::computeWorldToLocalMatrix	(	Matrix &	matrix,
		NodeVisitor *	nv
	)			const `[virtual]`

Reimplemented from osg::Transform.

const Quat& osg::CameraView::getAttitude ( ) const [inline]

Get the attitide of the camera view.

double osg::CameraView::getFieldOfView ( ) const [inline]

Get the field of view.

FieldOfViewMode osg::CameraView::getFieldOfViewMode ( ) const [inline]

Get the field of view mode.

double osg::CameraView::getFocalLength ( ) const [inline]

Get the focal length of the camera.

const Vec3d& osg::CameraView::getPosition ( ) const [inline]

Get the position of the camera view.

osg::CameraView::META_Node	(	osg	,
		CameraView
	)

void osg::CameraView::setAttitude ( const Quat & quat ) [inline]

Set the attitide of the camera view.

void osg::CameraView::setFieldOfView ( double fieldOfView ) [inline]

Set the field of view. The cameras field of view can be contrained to either the horizontal or vertex axis of the camera, or unconstrained in which case the camera/application are left to choose an appropriate field of view. The default value if 60 degrres.

void osg::CameraView::setFieldOfViewMode ( FieldOfViewMode mode ) [inline]

Set the field of view mode - controlling how the field of view of the camera is contrained by the CameaView settings.

void osg::CameraView::setFocalLength ( double focalLength ) [inline]

Set the focal length of the camera. A focal length of 0.0 indicates that the camera/application should determine the focal length. The default value is 0.0.

void osg::CameraView::setPosition ( const Vec3d & pos ) [inline]

Set the position of the camera view.
