Detailed Description

Component for rendering Open Inventor scene graphs.

This class provides Open Inventor rendering and message handling inside a Windows window. There is a routine to specify the scene to render. The scene is automatically rendered whenever anything under it changes (a data sensor is attached to the root of the scene), unless explicitly told not to do so (manual redraws). Users can also set Open Inventor rendering attributes such as the transparency algorithm, antialiasing on or off, etc. This class employs an SoSceneManager to manage rendering and message handling.

Windows messages that occur in the render area can be handled by the application, by the viewer (if this is really a viewer), or by the nodes in the scene graph. When a message occurs, it is first passed to the application message callback function registered with the setEventCallback() method on SoWinRenderArea. If this function does not exist or returns FALSE, the message is either used directly by the viewer or translated to an SoEvent for further scene graph processing. If the viewer does not handle the message, the SoEvent is sent to the scene graph by way of an SoHandleEventAction.

◆ render()

void SoWinRenderArea::render ( )

inline

Calling this forces the render area to be redrawn now.

It is not necessary to call this method if auto redraw is enabled (which is the default).

Definition at line 317 of file SoWinRenderArea.h.

◆ scheduleRedraw()

void SoWinRenderArea::scheduleRedraw ( )

Schedules a redraw to happen sometime soon (as opposed to immediately).

This can be used to compress multiple redraws.

Sends the event to be processed by the renderArea.

◆ setAutoRedraw()

void SoWinRenderArea::setAutoRedraw ( SbBool trueOrFalse )

◆ setBackgroundColor()

void SoWinRenderArea::setBackgroundColor ( const SbColor & c )

Sets the background color for this window.

Default is black (0,0,0).

◆ setBackgroundIndex()

void SoWinRenderArea::setBackgroundIndex ( int index )

inline

Sets the window background color when in color index mode.

Default is black (index 0)).

Definition at line 179 of file SoWinRenderArea.h.

◆ setClearBeforeRender()

void SoWinRenderArea::setClearBeforeRender	(	SbBool	trueOrFalse,
		SbBool	zbTrueOrFalse = `TRUE`
	)

inline

Enables/prevents window clearing from happening before a rendering starts (default is clear TRUE).

This can be useful to limit flickering when doing single buffering and geometry covers the entire window (used in the material editor). Also controls whether the depth buffer (sometimes called the Z buffer) is cleared before rendering.

Definition at line 269 of file SoWinRenderArea.h.

◆ setColorMap()

void SoWinRenderArea::setColorMap	(	int	startIndex,
		int	num,
		const SbColor *	colors
	)

Sets the colors to use when displaying in color index mode.

This will load the color map with the given colors at the starting index.

◆ setEventCallback()

void SoWinRenderArea::setEventCallback	(	SoWinRenderAreaEventCB *	fcn,
		void *	userData = `NULL`
	)

Windows messages which occur in the render area window are either directly handled by the viewer (when this is really a viewer) or automatically translated to SoEvents, then passed into the scene graph (via the SoHandleEventAction) so that live scene graph objects can handle the message (when viewers are not in viewing mode).

This method allows the application to register a callback for handling messages that occur in the window, instead of sending them to the viewers or down the graph. The callback is passed the Windows message, and should return TRUE if it handled the message. In this case the message will not be handled by the viewer and will not be sent to the scene graph. If the callback returns FALSE, then the message will be handled by the view and/or sent to the scene graph.

The following Windows events are sent to setEventCallback:

WM_LBUTTONDOWN
WM_MBUTTONDOWN
WM_RBUTTONDOWN
WM_LBUTTONUP
WM_MBUTTONUP
WM_RBUTTONUP
WM_MOUSEMOVE
WM_MOUSEWHEEL
WM_LBUTTONDBLCLK
WM_MBUTTONDBLCLK
WM_RBUTTONDBLCLK
WM_SETFOCUS
WM_KILLFOCUS
WM_COMMAND
WM_KEYDOWN
WM_SYSKEYDOWN
WM_KEYUP
WM_SYSKEYUP
WM_SIZE
WM_PAINT

◆ setFastEditSavePolicy()

void SoWinRenderArea::setFastEditSavePolicy	(	SoGLRenderAction::FastEditSavePolicy	policy,
		SbBool	fastEditDelayedObjects = `FALSE`
	)

Sets fast editing save policy to use when rendering.

The default is WHEN_NEEDED. Valid values are DISABLE, EACH_FRAME, and WHEN_NEEDED. See SoSeparator.

If fastEditDelayedObjects is set to TRUE, delayed objects won't be redrawn when editing the scene graph. It means that composition between delayed transparent objects and fast edit scene graph won't be correct but redrawing may be much faster. Default is FALSE.

◆ setFloatingColorBuffer()

void SoWinRenderArea::setFloatingColorBuffer	(	SbBool	enable,
		FloatColorBufferSize	size = `FLOAT_16_COLOR_BUFFER`
	)

virtual

Enables/disables floating point rendering using 16- or 32-bit components.

If TRUE, Open Inventor will automatically render to an offscreen floating point buffer, and copy the resulting image to the screen.

To determine if floating point rendering was successfully enabled, use getFloatingColorBuffer, below.

Using floating point rendering can improve image quality, particularly when many objects are being blended, for example, in volume rendering. This is a convenience method as you could accomplish the same results setting up a graphic template.

Reimplemented from SoWinGLWidget.

◆ setGLRenderAction()

void SoWinRenderArea::setGLRenderAction ( SoGLRenderAction * ra )

Sets the GL render action to use.

This is used for example to set selection highlighting with the SoBoxHighlightRenderAction, SoHaloHighlightRenderAction and SoLineHighlightRenderAction classes.

Note: Properties of the previous render action, for example transparency type, are not automatically copied to the new render action. The application must explicitly set the desired properties of the new render action.

◆ setInvalidateCacheMode()

void SoWinRenderArea::setInvalidateCacheMode ( SoGLRenderAction::InvalidateCacheMode icm )

Enables or disables the invalidation of render caches.

When set to ALWAYS, the caches are invalidated for each SoSeparator node before its children are traversed. No new caches will be built. This value forces all nodes to be visited during each render traversal.
When set to ONCE, the caches are invalidated for each SoSeparator node before its children are traversed. The invalidate cache mode is automatically changed to OFF at the end of the traversal.
When set to OFF (default), caches are managed by their respective render caching nodes in the usual way.

This method is useful to force all nodes to be visited during render traversal.

◆ setMPEGRecorder()

virtual void SoWinRenderArea::setMPEGRecorder ( SoMPEGRenderer * recorder )

inlinevirtual

Sets the recorder used for MPEG encoding.

Default is none.

Parameters

recorder the recorder to be used.

Definition at line 462 of file SoWinRenderArea.h.

◆ setPostRenderCallback()

void SoWinRenderArea::setPostRenderCallback	(	SoWinRenderAreaRenderCB *	fcn,
		void *	userData = `NULL`
	)

inline

Specifies a function to be called after the Open Inventor render traversal and immediately before the OpenGL buffer swap.

Generally the application should not modify Open Inventor state in these callbacks, but they can be useful for special effects using OpenGL calls.

When the callback function is called, Open Inventor has completed normal rendering (including delayed transparent objects, multi-pass, etc), but no "end of frame" calls (glFlush, glFinish, SwapBuffers...) have been made. The function should return TRUE if "end of frame" handling has been done by the application (Open Inventor will do nothing in this case). If FALSE is returned, Open Inventor will do its normal end of frame calls (normally calling SwapBuffers).

Definition at line 429 of file SoWinRenderArea.h.

◆ setRedrawPriority()

void SoWinRenderArea::setRedrawPriority ( unsigned long priority )

inline

Sets the priority of the redraw sensor.

Definition at line 301 of file SoWinRenderArea.h.

◆ setSceneGraph()

virtual void SoWinRenderArea::setSceneGraph ( SoNode * newScene )

virtual

Sets the scene graph to be rendered in this component's window.

Reimplemented in SoWinViewer.

◆ setSceneManager()

void SoWinRenderArea::setSceneManager ( SoSceneManager * sm )

Sets the normal scene manager.

Note: For convenience most of the SoSceneManager methods have already been added to this class.

◆ setTransparencyType()

void SoWinRenderArea::setTransparencyType ( SoGLRenderAction::TransparencyType type )

Sets the algorithm for rendering transparent objects.

Default is NO_SORT. See SoGLRenderAction for possible transparency types. See also SoGLRenderAction::TransparencyType.

Note: When using OPAQUE_FIRST, SORTED_OBJECT or SORTED_PIXEL transparency, the depth buffer is not updated (depth buffer writes are disabled) while rendering transparent objects. As a result complex 3D shapes may not be rendered correctly.

◆ setViewportRegion()

void SoWinRenderArea::setViewportRegion ( const SbViewportRegion & newRegion )

inline

Sets viewport region to use for rendering.

Definition at line 196 of file SoWinRenderArea.h.

◆ unregisterDevice()

void SoWinRenderArea::unregisterDevice ( SoWinDevice * d )

Unregisters interest in devices.

When a device is registered, messages from that device will be processed by the render area, and passed into the scene graph. Messages from unregistered devices will be ignored.
