Constructor.

Virtual destructor.

Set up-direction vector for the camera viewpoint.

Return up-direction vector for the camera viewpoint.

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.

getCamera()

Reimplemented from SoQtViewer.

Reimplemented in SoQtFlyViewer.

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

See also

resetToHomePosition()

Reimplemented from SoQtViewer.

Restore the saved camera settings.

See also

saveHomePosition()

Reimplemented from SoQtViewer.

Reimplemented in SoQtFlyViewer.

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

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.

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.

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

Reimplemented from SoQtViewer.

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.

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