Detailed Description

The SoWinFlyViewer class implements controls for moving the camera in a "flying" motion.


  • Left mouse button increases the speed.

  • Middle mouse button decreases the speed.

  • Left and middle mouse button together sets the speed to zero.

  • "s" puts the viewer in seek mode. Click some geometry with the left mouse button to start the seek zoom animation. (Hitting "s" again before clicking will cancel the seek operation.)

  • "u" puts the viewer in up-vector pick mode. Click some geometry with the left mouse button to set the camera's up-vector to the normal vector of the face you pick. (Hitting "u" again before clicking will cancel the pick operation.)

  • The control key stops the flying and lets you tilt the camera by moving the pointer.

Constructor & Destructor Documentation

◆ SoWinFlyViewer() [1/2]

SoWinFlyViewer::SoWinFlyViewer ( HWND  parent = NULL,
const char *  name = NULL,
SbBool  embed = TRUE,
SoWinFullViewer::BuildFlag  flag = BUILD_ALL,
SoWinViewer::Type  type = BROWSER 

Public constructor.

◆ ~SoWinFlyViewer()

SoWinFlyViewer::~SoWinFlyViewer ( )

Virtual constructor.

◆ SoWinFlyViewer() [2/2]

SoWinFlyViewer::SoWinFlyViewer ( HWND  parent,
const char *const  name,
SbBool  embed,
SoWinFullViewer::BuildFlag  flag,
SoWinViewer::Type  type,
SbBool  build 

Protected constructor, used by viewer components derived from the SoWinFlyViewer.

Member Function Documentation

◆ setViewing()

void SoWinFlyViewer::setViewing ( SbBool  enable)

Set view mode.

If the view mode is on, user events will be caught and used to influence the camera position / orientation. If view mode is off, all events in the viewer canvas (like for instance keypresses or mouse clicks and -movements) will be passed along to the scene graph.

Default is to have the view mode active.

See also

Reimplemented from SoWinFullViewer.

◆ viewAll()

void SoWinFlyViewer::viewAll ( void  )

Reposition the current camera so we can see the complete scene.

Reimplemented from SoWinViewer.

◆ resetToHomePosition()

void SoWinFlyViewer::resetToHomePosition ( void  )

Restore the saved camera settings.

See also

Reimplemented from SoWinConstrainedViewer.

◆ setCamera()

void SoWinFlyViewer::setCamera ( SoCamera cam)

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.

See also

Reimplemented from SoWinConstrainedViewer.

◆ setCursorEnabled()

void SoWinFlyViewer::setCursorEnabled ( SbBool  on)

Set whether or not the mouse cursor representation should be visible in the viewer canvas.

Default value is on.

See also

Reimplemented from SoWinViewer.

◆ setCameraType()

void SoWinFlyViewer::setCameraType ( SoType  t)

When the viewer has to make its own camera as a result of the graph passed to setSceneGraph() not containing any camera nodes, this call can be made in advance to decide which type the camera will be of.

Default is to use an SoPerspectiveCamera.

If this method is called when there is a scene graph and a camera already set up, it will delete the old camera and set up a camera with the new type if the t type is different from that of the current camera.

See also

Reimplemented from SoWinViewer.

◆ getDefaultWidgetName()

const char * SoWinFlyViewer::getDefaultWidgetName ( void  ) const

This method returns the default name of a component widget class.

It should be overridden by derived non-abstract classes for the topmost widget in the component to have a proper name.

Reimplemented from SoWinRenderArea.

◆ getDefaultTitle()

const char * SoWinFlyViewer::getDefaultTitle ( void  ) const

This method returns the default window caption string of the component.

It should be overridden by derived non-abstract classes so the window and pop-up menu will get a proper title.

Reimplemented from SoWinRenderArea.

◆ getDefaultIconTitle()

const char * SoWinFlyViewer::getDefaultIconTitle ( void  ) const

This method returns the default icon title of the component.

It should be overridden by derived non-abstract classes so icons will get proper titles.

Reimplemented from SoWinRenderArea.

◆ processSoEvent()

SbBool SoWinFlyViewer::processSoEvent ( const SoEvent *const  event)

Toolkit-native events are tried to convert to Coin-generic events in the SoWinRenderArea::processEvent() method. If this succeeds, they are forwarded to this method.

This is a virtual method, and is overridden in its subclasses to catch events of particular interest to the viewer classes, for instance.

Return TRUE if the event was processed. If not it should be passed on further up in the inheritance hierarchy by the caller. This last point is extremely important to take note of if you are expanding the toolkit with your own viewer class.

This method is not part of the original SGI InventorXt API. Note that you can still override the toolkit-native processEvent() method instead of this "generic" method.

Reimplemented from SoWinFullViewer.

◆ setSeekMode()

void SoWinFlyViewer::setSeekMode ( SbBool  enable)

Put the viewer in or out of "waiting-to-seek" mode.

If the user performs a mouse button click when the viewer is in "waiting-to-seek" mode, the camera will be repositioned so the camera focal point lies on the point of the geometry under the mouse cursor.

See also
isSeekMode(), setDetailSeek()

Reimplemented from SoWinViewer.

◆ actualRedraw()

void SoWinFlyViewer::actualRedraw ( void  )

This method instantly redraws the normal (non-overlay) scene graph by calling SoSceneManager::render().

Subclasses may override this method to add their own rendering before or after Coin renders its scene graph.

The following is a complete example that demonstrates one way of adding both a background image and foreground (overlay) geometry to the "normal" rendering:

// This example shows how to put a permanent background image on
// your viewer canvas, below the 3D graphics, plus overlay
// foreground geometry. Written by mortene.

◆ rightWheelMotion()

void SoWinFlyViewer::rightWheelMotion ( float  value)

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

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

Reimplemented from SoWinFullViewer.

◆ afterRealizeHook()

void SoWinFlyViewer::afterRealizeHook ( void  )

A function "hook" / callback invoked just after the window for the component has been realized.

Override this if you need specific initialization for your own component or viewer class to happen right after it has been made visible, but remember to call upwards in the inheritance hierarchy:

// [own initialization here]
