Detailed Description

The SoXtConstrainedViewer 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 SoXtConstrainedViewer::setUpDirection()) or the end-user, through interaction mechanisms defined by the subclasses.

Constructor & Destructor Documentation

◆ SoXtConstrainedViewer()

SoXtConstrainedViewer::SoXtConstrainedViewer	(	Widget	parent,
		const char *const	name,
		SbBool	embed,
		SoXtFullViewer::BuildFlag	flag,
		SoXtViewer::Type	type,
		SbBool	build
	)

protected

Constructor.

◆ ~SoXtConstrainedViewer()

SoXtConstrainedViewer::~SoXtConstrainedViewer ( )

protected

Virtual destructor.

Member Function Documentation

◆ setUpDirection()

void SoXtConstrainedViewer::setUpDirection ( const SbVec3f & dir )

Set up-direction vector for the camera viewpoint.

◆ getUpDirection()

const SbVec3f & SoXtConstrainedViewer::getUpDirection ( void ) const

Return up-direction vector for the camera viewpoint.

◆ setCamera()

void SoXtConstrainedViewer::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 from SoXtViewer.

Reimplemented in SoXtFlyViewer.

◆ saveHomePosition()

void SoXtConstrainedViewer::saveHomePosition ( void )

virtual

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

See also: resetToHomePosition()

Reimplemented from SoXtViewer.

◆ resetToHomePosition()

void SoXtConstrainedViewer::resetToHomePosition ( void )

virtual

Restore the saved camera settings.

See also: saveHomePosition()

Reimplemented from SoXtViewer.

Reimplemented in SoXtFlyViewer.

◆ tiltCamera()

void SoXtConstrainedViewer::tiltCamera ( float delta )

protectedvirtual

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

◆ bottomWheelMotion()

void SoXtConstrainedViewer::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 SoXtFullViewer.

◆ leftWheelMotion()

void SoXtConstrainedViewer::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 SoXtFullViewer.

◆ changeCameraValues()

void SoXtConstrainedViewer::changeCameraValues ( SoCamera * camera )

protectedvirtual

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

Reimplemented from SoXtViewer.

◆ findUpDirection()

void SoXtConstrainedViewer::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 SoXtConstrainedViewer::checkForCameraUpConstrain ( void )

protected

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