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

Constructor.

SoQtConstrainedViewer::~SoQtConstrainedViewer () [protected]

Virtual destructor.

Member Function Documentation

void SoQtConstrainedViewer::setUpDirection (const SbVec3f & dir)

Set up-direction vector for the camera viewpoint.

const SbVec3f & SoQtConstrainedViewer::getUpDirection (void) const

Return up-direction vector for the camera viewpoint.

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 scene graph. 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 scene graph to find a camera to use. If no camera is available in the scene graph at all, it will set up its own camera.

void SoQtConstrainedViewer::saveHomePosition (void) [virtual]

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

resetToHomePosition()

Reimplemented from SoQtViewer.

void SoQtConstrainedViewer::resetToHomePosition (void) [virtual]

Restore the saved camera settings.

void SoQtConstrainedViewer::tiltCamera (float delta) [protected], [virtual]

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

void SoQtConstrainedViewer::bottomWheelMotion (float value) [protected], [virtual]

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.

bottomWheelStart(), bottomWheelFinish()

leftWheelStart(), rightWheelStart()

Reimplemented from SoQtFullViewer.

void SoQtConstrainedViewer::leftWheelMotion (float value) [protected], [virtual]

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.

leftWheelStart(), leftWheelFinish()

bottomWheelStart(), rightWheelStart()

Reimplemented from SoQtFullViewer.

void SoQtConstrainedViewer::changeCameraValues (SoCamera * camera) [protected], [virtual]

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

Reimplemented from SoQtViewer.

void SoQtConstrainedViewer::findUpDirection (SbVec2s mouselocation) [protected]

Executes a ray pick at the given mouse pointer location and sets the viewer's camera up-vector direction to the normal vector of the picked geometry.

void SoQtConstrainedViewer::checkForCameraUpConstrain (void) [protected]

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