Constructor. Sets up default SoGLRenderAction and SoHandleEventAction instances.

Destructor.

Render the scene graph.

If clearwindow is TRUE, clear the rendering buffer before drawing. If clearzbuffer is TRUE, clear the depth buffer values before rendering. Both of these arguments should normally be TRUE, but they can be set to FALSE to optimize for special cases (e.g. when doing wireframe rendering one doesn't need a depth buffer).

Render method used for thread safe rendering.

Since only one thread can use an SoGLRenderAction, this method enables you to supply your own thread-specific SoGLRenderAction to be used for rendering the scene.

If initmatrices is TRUE, the OpenGL model and projection matrices will be initialized to identity matrices before applying the action.

If clearwindow is TRUE, clear the rendering buffer before drawing. If clearzbuffer is TRUE, clear the depth buffer values before rendering.

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Since

Coin 2.0

Sets the camera to be used.

Returns the current camera.

Process the given event by applying an SoHandleEventAction on the scene graph.

Reinitialize after parameters affecting the OpenGL context has changed.

Redraw at first opportunity as system becomes idle.

Multiple calls to this method before an actual redraw has taken place will only result in a single redraw of the scene.

Set the node which is top of the scene graph we're managing. The sceneroot node reference count will be increased by 1, and any previously set scene graph top node will have it's reference count decreased by 1.

See also

getSceneGraph()

Returns pointer to root of scene graph.

Update window size of our SoGLRenderAction's viewport settings.

Note that this will only change the information about window dimensions, the actual viewport size and origin (ie the rectangle which redraws are confined to) will stay the same.

See also

setViewportRegion()

Returns the current render action window size.

See also

setWindowSize()

Set size of rendering area for the viewport within the current window.

Returns size of render area.

Set only the origin of the viewport region within the rendering window.

See also

setViewportRegion(), setWindowSize()

Returns origin of rendering area viewport.

See also

setOrigin()

Update our SoGLRenderAction's viewport settings.

This will change both the information about window dimensions and the actual viewport size and origin.

See also

setWindowSize()

Returns current viewport region used by the renderaction and the event handling.

See also

setViewportRegion()

Sets color of rendering canvas.

Returns color used for clearing the rendering area before rendering the scene.

Set index of background color in the color lookup table if rendering in colorindex mode.

Note: colorindex mode is not supported yet in Coin.

Returns index of colormap for background filling.

See also

setBackgroundIndex()

Turn RGB truecolor mode on or off. If you turn truecolor mode off, colorindex mode will be used instead.

Returns the 'truecolor or colorindex' mode flag.

Activate rendering and event handling. Default is off.

Deactive rendering and event handling.

Set the callback function f to invoke when rendering the scene. userdata will be passed as the first argument of the function.

Returns TRUE if the SoSceneManager automatically redraws the scene upon detecting changes in the scene graph.

The automatic redraw is turned on and off by setting either a valid callback function with setRenderCallback(), or by passing NULL.

Set up the redraw priority for the SoOneShotSensor used to trigger redraws. By setting this lower than for your own sensors, you can make sure some code is always run before redraw happens.

See also

SoDelayQueueSensor

Returns value of priority on the redraw sensor.

Turn antialiased rendering on or off.

See documentation for SoGLRenderAction::setSmoothing() and SoGLRenderAction::setNumPasses().

Returns rendering pass information.

See also

setAntialiasing()

Set the action to use for rendering. Overrides the default action made in the constructor.

Returns pointer to render action.

Set the action to use for rendering audio. Overrides the default action made in the constructor.

Returns pointer to audio render action.

Set the action to use for event handling. Overrides the default action made in the constructor.

Returns pointer to event handler action.

Returns the default priority of the redraw sensor.

See also

SoDelayQueueSensor, setRedrawPriority()

Set whether or not for SoSceneManager instances to 'touch' the global realTime field after a redraw. If this is not done, redrawing when animating the scene will only happen as fast as the realTime interval goes (which defaults to 12 times a second).

See also

SoDB::setRealTimeInterval()

Returns whether or not we automatically notifies everything connected to the realTime field after a redraw.

Returns the active flag.

Do an immediate redraw by calling the redraw callback function.
