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 accumulate the view matrix from this NodePath.

void osg::CameraView::setAttitude ( const Quat & quat )

inline

Set the attitude of the camera view.

Definition at line 52 of file CameraView.h.

void osg::CameraView::setFieldOfView ( double fieldOfView )

inline

Set the field of view. The camera's field of view can be constrained to either the horizontal or vertical 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 degrees.

Definition at line 61 of file CameraView.h.

void osg::CameraView::setFieldOfViewMode ( FieldOfViewMode mode )

inline

Set the field of view mode - controlling how the field of view of the camera is constrained by the CameraView settings.

Definition at line 74 of file CameraView.h.

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.

Definition at line 82 of file CameraView.h.

void osg::CameraView::setPosition ( const Vec3d & pos )

inline

Set the position of the camera view.
