Detailed Description

The SoQtConstrainedViewer class is the superclass for viewers with constrains on the viewpoint.

This abstract viewer class adds new methods to keep the camera in an upright position according to some arbitrary up-direction. The up-direction can be decided by either the application programmer (by using SoQtConstrainedViewer::setUpDirection()) or the end-user, through interaction mechanisms defined by the subclasses.

Constructor & Destructor Documentation

◆ SoQtConstrainedViewer()

SoQtConstrainedViewer::SoQtConstrainedViewer ( QWidget *  parent,
const char *const  name,
SbBool  embed,
SoQtFullViewer::BuildFlag  flag,
SoQtViewer::Type  type,
SbBool  build 
)
protected

Constructor.

◆ ~SoQtConstrainedViewer()

SoQtConstrainedViewer::~SoQtConstrainedViewer ( )
protected

Virtual destructor.

Member Function Documentation

◆ setUpDirection()

void SoQtConstrainedViewer::setUpDirection ( const SbVec3f dir)

Set up-direction vector for the camera viewpoint.

◆ getUpDirection()

const SbVec3f & SoQtConstrainedViewer::getUpDirection ( void  ) const

Return up-direction vector for the camera viewpoint.

◆ setCamera()

void SoQtConstrainedViewer::setCamera ( SoCamera cam)
virtual

Set the camera we want the viewer to manipulate when interacting with the viewer controls.

The camera passed in as an argument to this method must already be part of the viewer's scenegraph. You do not inject viewpoint cameras to the viewer with this method.

You should rather insert a camera into the scene graph first (if necessary, often one will be present already), then register it as the camera used by the viewer controls with this method.

If the application code doesn't explicitly set up a camera through this method, the viewer will automatically scan through the scenegraph to find a camera to use. If no camera is available in the scenegraph at all, it will set up it's own camera.

Reimplemented in SoQtFlyViewer.

◆ saveHomePosition()

void SoQtConstrainedViewer::saveHomePosition ( void  )
virtual

Store the current camera settings for later retrieval with resetToHomePosition().

See also
resetToHomePosition()

Reimplemented from SoQtViewer.

◆ resetToHomePosition()

void SoQtConstrainedViewer::resetToHomePosition ( void  )
virtual

Restore the saved camera settings.

See also
saveHomePosition()

Reimplemented from SoQtViewer.

Reimplemented in SoQtFlyViewer.

◆ tiltCamera()

void SoQtConstrainedViewer::tiltCamera ( float  delta)
protectedvirtual

This method tilts the camera delta degrees closer to the up direction.

◆ bottomWheelMotion()

void SoQtConstrainedViewer::bottomWheelMotion ( float  value)
protectedvirtual

Called repeatedly as the user drags the thumbwheel in the bottom frame. Override this method in subclassed viewers to provide your own functionality on the thumbwheel.

See also
bottomWheelStart(), bottomWheelFinish()
leftWheelStart(), rightWheelStart()

Reimplemented from SoQtFullViewer.

◆ leftWheelMotion()

void SoQtConstrainedViewer::leftWheelMotion ( float  value)
protectedvirtual

Called repeatedly as the user drags the thumbwheel in the left frame. Override this method in subclassed viewers to provide your own functionality on the thumbwheel.

See also
leftWheelStart(), leftWheelFinish()
bottomWheelStart(), rightWheelStart()

Reimplemented from SoQtFullViewer.

◆ changeCameraValues()

void SoQtConstrainedViewer::changeCameraValues ( SoCamera camera)
protectedvirtual

Copies the settings of camera into our current camera. Cameras must be of the same class type.

Reimplemented from SoQtViewer.

◆ findUpDirection()

void SoQtConstrainedViewer::findUpDirection ( SbVec2s  mouselocation)
protected

Executes a raypick at the given mousepointer location and sets the viewer's camera up-vector direction to the normal vector of the picked geometry.

◆ checkForCameraUpConstrain()

void SoQtConstrainedViewer::checkForCameraUpConstrain ( void  )
protected

If necessary, "tilts" the camera sideways so the up-direction is heeded.
