inlineinherited

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Deprecated:: This function is deprecated as behavior for dst.size < RenderTarget.size was inconsistent in previous versions of Ogre.

Sometimes the whole rect was used as a source, sometimes the rect with the size equal to the size of destination rect but located in the top left corner of the render target, sometimes the destination rect itself. Use the overload with explicitly specified source and destination boxes instead.

◆ requiresTextureFlipping()

bool Ogre::D3D11RenderWindowBase::requiresTextureFlipping ( ) const

inlinevirtualinherited

Implements Ogre::RenderTarget.

◆ _validateStereo()

void Ogre::D3D11RenderWindowBase::_validateStereo ( )

inherited

Validate the type of stereo that is enabled for this window.

◆ getViewPointToPixelScale()

virtual float Ogre::RenderWindow::getViewPointToPixelScale ( )

inlinevirtualinherited

Many windowing systems that support HiDPI displays use special points to specify size of the windows and controls, so that windows and controls with hardcoded sizes does not become too small on HiDPI displays.

Such points have constant density ~ 100 points per inch (probably 96 on Windows and 72 on Mac), that is independent of pixel density of real display, and are used through the all windowing system.

Sometimes, such view points are choosen bigger for output devices that are viewed from larger distances, like 30" TV comparing to 30" monitor, therefore maintaining constant points angular density rather than constant linear density.

In any case, all such windowing system provides the way to convert such view points to pixels, be it DisplayProperties::LogicalDpi on WinRT or backingScaleFactor on MacOSX. We use pixels consistently through the Ogre, but window/view management functions takes view points for convenience, as does the rest of windowing system. Such parameters are named using xxxxPt pattern, and should not be mixed with pixels without being converted using getViewPointToPixelScale() function.

Sometimes such scale factor can change on-the-fly, for example if window is dragged to monitor with different DPI. In such situation, window size in view points is usually preserved by windowing system, and Ogre should adjust pixel size of RenderWindow.

◆ setFullscreen()

virtual void Ogre::RenderWindow::setFullscreen	(	bool	fullScreen,
		unsigned int	widthPt,
		unsigned int	heightPt
	)

inlinevirtualinherited

Alter fullscreen mode options.

Note: Nothing will happen unless the settings here are different from the current settings.

Parameters

fullScreen	Whether to use fullscreen mode or not.
widthPt	The new width to use
heightPt	The new height to use

Reimplemented in Ogre::D3D9RenderWindow.

◆ windowMovedOrResized()

virtual void Ogre::RenderWindow::windowMovedOrResized ( )

Remarks: You don't need to call this unless you created the window externally.

Reimplemented in Ogre::D3D9RenderWindow.

◆ isVisible()

virtual bool Ogre::RenderWindow::isVisible ( void ) const

inlinevirtualinherited

Indicates whether the window is visible (not minimized or obscured)

Reimplemented in Ogre::D3D9RenderWindow.

◆ setVisible()

virtual void Ogre::RenderWindow::setVisible ( bool visible )

inlinevirtualinherited

Set the visibility state.

◆ setHidden()

virtual void Ogre::RenderWindow::setHidden ( bool hidden )

inlinevirtualinherited

Hide (or show) the window.

If called with hidden=true, this will make the window completely invisible to the user.

Remarks: Setting a window to hidden is useful to create a dummy primary RenderWindow hidden from the user so that you can create and recreate your actual RenderWindows without having to recreate all your resources.

Reimplemented in Ogre::D3D9RenderWindow.

◆ setVSyncInterval() [2/2]

virtual void Ogre::RenderWindow::setVSyncInterval ( unsigned int interval )

inlinevirtualinherited

◆ isPrimary()

virtual bool Ogre::RenderWindow::isPrimary ( void ) const

virtualinherited

Indicates whether the window is the primary window.

The primary window is special in that it is destroyed when ogre is shut down, and cannot be destroyed directly. This is the case because it holds the context for vertex, index buffers and textures.

Reimplemented from Ogre::RenderTarget.

◆ isFullScreen()

virtual bool Ogre::RenderWindow::isFullScreen ( void ) const

virtualinherited

Returns true if window is running in fullscreen mode.

◆ getMetrics() [1/2]

inherited

Returns true if the window will automatically de-activate itself when it loses focus.

◆ setDeactivateOnFocusChange()

void Ogre::RenderWindow::setDeactivateOnFocusChange ( bool deactivate )

inherited

Indicates whether the window will automatically deactivate itself when it loses focus.

inherited

Sets the pool ID this RenderTarget should query from.

Default value is POOL_DEFAULT. Set to POOL_NO_DEPTH to avoid using a DepthBuffer (or manually controlling it)

See also: DepthBuffer

Remarks: Changing the pool Id will cause the current depth buffer to be detached unless the old id and the new one are the same

See also: DepthBuffer::_setPoolId())

Reimplemented in Ogre::GLFBORenderTexture, Ogre::GL3PlusFBORenderTexture, Ogre::GLES2FBORenderTexture, Ogre::GL3PlusFBOMultiRenderTarget, Ogre::GLES2FBOMultiRenderTarget, and Ogre::GLFBOMultiRenderTarget.

◆ update()

virtual void Ogre::RenderTarget::update ( bool swapBuffers = true )

virtualinherited

Tells the target to update it's contents.

Remarks: If OGRE is not running in an automatic rendering loop (started using Root::startRendering), the user of the library is responsible for asking each render target to refresh. This is the method used to do this. It automatically re-renders the contents of the target using whatever cameras have been pointed at it (using Camera::setRenderTarget).

: This allows OGRE to be used in multi-windowed utilities and for contents to be refreshed only when required, rather than constantly as with the automatic rendering loop.

Parameters

swapBuffers For targets that support double-buffering, if set to true, the target will immediately swap it's buffers after update. Otherwise, the buffers are not swapped, and you have to call swapBuffers yourself sometime later. You might want to do this on some rendersystems which pause for queued rendering commands to complete before accepting swap buffers calls - so you could do other CPU tasks whilst the queued commands complete. Or, you might do this if you want custom control over your windows, such as for externally created windows.

Reimplemented in Ogre::D3D9RenderTexture, and Ogre::D3D9MultiRenderTarget.

◆ addViewport()

virtual Viewport* Ogre::RenderTarget::addViewport	(	Camera *	cam,
		int	ZOrder = `0`,
		float	left = `0.0f`,
		float	top = `0.0f`,
		float	width = `1.0f`,
		float	height = `1.0f`
	)

virtualinherited

Adds a viewport to the rendering target.

Remarks: A viewport is the rectangle into which rendering output is sent. This method adds a viewport to the render target, rendering from the supplied camera. The rest of the parameters are only required if you wish to add more than one viewport to a single rendering target. Note that size information passed to this method is passed as a parametric, i.e. it is relative rather than absolute. This is to allow viewports to automatically resize along with the target.

Parameters

cam	The camera from which the viewport contents will be rendered (mandatory)
ZOrder	The relative order of the viewport with others on the target (allows overlapping viewports i.e. picture-in-picture). Higher Z-orders are on top of lower ones. The actual number is irrelevant, only the relative Z-order matters (you can leave gaps in the numbering)
left	The relative position of the left of the viewport on the target, as a value between 0 and 1.
top	The relative position of the top of the viewport on the target, as a value between 0 and 1.
width	The relative width of the viewport on the target, as a value between 0 and 1.
height	The relative height of the viewport on the target, as a value between 0 and 1.

virtual void Ogre::RenderTarget::removeViewport ( int ZOrder )

virtualinherited

Removes a viewport at a given Z-order.

◆ removeAllViewports()

virtual void Ogre::RenderTarget::removeAllViewports ( void )

virtualinherited

Removes all viewports on this target.

◆ getStatistics() [1/2]

		float &	avgFPS,
		float &	bestFPS,
		float &	worstFPS
	)		const

virtualinherited

Retieves details of current rendering performance.

Remarks: If the user application wishes to do it's own performance display, or use performance for some other means, this method allows it to retrieve the statistics.

Parameters

lastFPS	Pointer to a float to receive the number of frames per second (FPS) based on the last frame rendered.
avgFPS	Pointer to a float to receive the FPS rating based on an average of all the frames rendered since rendering began (the call to Root::startRendering).
bestFPS	Pointer to a float to receive the best FPS rating that has been achieved since rendering began.
worstFPS	Pointer to a float to receive the worst FPS rating seen so far.

◆ addListener()

virtual void Ogre::RenderTarget::addListener ( RenderTargetListener * listener )

virtualinherited

Add a listener to this RenderTarget which will be called back before & after rendering.

Remarks: If you want notifications before and after a target is updated by the system, use this method to register your own custom RenderTargetListener class. This is useful for potentially adding your own manual rendering commands before and after the 'normal' system rendering.

NB this should not be used for frame-based scene updates, use Root::addFrameListener for that.

◆ insertListener()

virtual void Ogre::RenderTarget::insertListener	(	RenderTargetListener *	listener,
		const unsigned int	pos = `0`
	)

virtualinherited

Removes a RenderTargetListener previously registered using addListener.

◆ removeAllListeners()

virtual void Ogre::RenderTarget::removeAllListeners ( void )

virtualinherited

Removes all listeners from this instance.

◆ setPriority()

virtual void Ogre::RenderTarget::setPriority ( uchar priority )

inlinevirtualinherited

Sets the priority of this render target in relation to the others.

Remarks: This can be used in order to schedule render target updates. Lower priorities will be rendered first. Note that the priority must be set at the time the render target is attached to the render system, changes afterwards will not affect the ordering.

◆ getPriority()

virtual uchar Ogre::RenderTarget::getPriority ( ) const

inlinevirtualinherited

Gets the priority of a render target.

◆ setActive()

virtual void Ogre::RenderTarget::setActive ( bool state )

virtualinherited

Used to set the active state of the render target.

◆ setAutoUpdated()

virtual void Ogre::RenderTarget::setAutoUpdated ( bool autoupdate )

virtualinherited

Sets whether this target should be automatically updated if Ogre's rendering loop or Root::_updateAllRenderTargets is being used.

Remarks: By default, if you use Ogre's own rendering loop (Root::startRendering) or call Root::_updateAllRenderTargets, all render targets are updated automatically. This method allows you to control that behaviour, if for example you have a render target which you only want to update periodically.

Parameters

autoupdate If true, the render target is updated during the automatic render loop or when Root::_updateAllRenderTargets is called. If false, the target is only updated when its update() method is called explicitly.

◆ isAutoUpdated()

virtual bool Ogre::RenderTarget::isAutoUpdated ( void ) const

virtualinherited

Gets whether this target is automatically updated if Ogre's rendering loop or Root::_updateAllRenderTargets is being used.

◆ writeContentsToFile()

void Ogre::RenderTarget::writeContentsToFile ( const String & filename )

inherited

Writes the current contents of the render target to the named file.

◆ writeContentsToTimestampedFile()

virtual String Ogre::RenderTarget::writeContentsToTimestampedFile	(	const String &	filenamePrefix,
		const String &	filenameSuffix
	)

virtualinherited

Writes the current contents of the render target to the (PREFIX)(time-stamp)(SUFFIX) file.

Returns: the name of the file used.

◆ getTriangleCount()

virtual size_t Ogre::RenderTarget::getTriangleCount ( void ) const

virtualinherited

Deprecated:: use getStatistics()

◆ getBatchCount()

virtual size_t Ogre::RenderTarget::getBatchCount ( void ) const

virtualinherited

Deprecated:: use getStatistics()

◆ _notifyCameraRemoved()

virtual void Ogre::RenderTarget::_notifyCameraRemoved ( const Camera * cam )

virtualinherited

Utility method to notify a render target that a camera has been removed, incase it was referring to it as a viewer.

◆ isStereoEnabled()

virtual bool Ogre::RenderTarget::isStereoEnabled ( void ) const

virtualinherited

Indicates whether stereo is currently enabled for this target.

Default is false.

◆ isHardwareGammaEnabled()

virtual bool Ogre::RenderTarget::isHardwareGammaEnabled ( ) const

inlinevirtualinherited

Indicates whether on rendering, linear colour space is converted to sRGB gamma colour space.

This is the exact opposite conversion of what is indicated by Texture::isHardwareGammaEnabled, and can only be enabled on creation of the render target. For render windows, it's enabled through the 'gamma' creation misc parameter. For textures, it is enabled through the hwGamma parameter to the create call.

◆ getFSAA()

virtual uint Ogre::RenderTarget::getFSAA ( ) const

inlinevirtualinherited

Indicates whether multisampling is performed on rendering and at what level.

◆ getFSAAHint()

virtual const String& Ogre::RenderTarget::getFSAAHint ( ) const

inlinevirtualinherited

Gets the FSAA hint (.

See also: Root::createRenderWindow)

◆ _getImpl()

virtual Impl* Ogre::RenderTarget::_getImpl ( )

virtualinherited

Get rendersystem specific interface for this RenderTarget.

This is used by the RenderSystem to (un)bind this target, and to get specific information like surfaces and framebuffer objects.

◆ _beginUpdate()

virtual void Ogre::RenderTarget::_beginUpdate ( )

virtualinherited

Method for manual management of rendering : fires 'preRenderTargetUpdate' and initialises statistics etc.

Remarks

_beginUpdate resets statistics and fires 'preRenderTargetUpdate'.
_updateViewport renders the given viewport (even if it is not autoupdated), fires preViewportUpdate and postViewportUpdate and manages statistics.
_updateAutoUpdatedViewports renders only viewports that are auto updated, fires preViewportUpdate and postViewportUpdate and manages statistics.
_endUpdate() ends statistics calculation and fires postRenderTargetUpdate.

you can use it like this for example :

    renderTarget->_beginUpdate();
    renderTarget->_updateViewport(1); // which is not auto updated
    renderTarget->_updateViewport(2); // which is not auto updated
    renderTarget->_updateAutoUpdatedViewports();
    renderTarget->_endUpdate();
    renderTarget->swapBuffers();

Please note that in that case, the zorder may not work as you expect, since you are responsible for calling _updateViewport in the correct order.

Reimplemented in Ogre::D3D9RenderWindow.

◆ _updateViewport() [1/2]

virtual void Ogre::RenderTarget::_updateViewport	(	int	zorder,
		bool	updateStatistics = `true`
	)

virtualinherited

Method for manual management of rendering - renders the given viewport (even if it is not autoupdated)

Remarks: This also fires preViewportUpdate and postViewportUpdate, and manages statistics. You should call it between _beginUpdate() and _endUpdate().

See also: _beginUpdate for more details.

Parameters

zorder	The zorder of the viewport to update.
updateStatistics	Whether you want to update statistics or not.

◆ _updateViewport() [2/2]

virtual void Ogre::RenderTarget::_updateViewport	(	Viewport *	viewport,
		bool	updateStatistics = `true`
	)

virtualinherited

Method for manual management of rendering - renders the given viewport (even if it is not autoupdated)

Remarks: This also fires preViewportUpdate and postViewportUpdate, and manages statistics if needed. You should call it between _beginUpdate() and _endUpdate().

See also: _beginUpdate for more details.

Parameters

viewport	The viewport you want to update, it must be bound to the rendertarget.
updateStatistics	Whether you want to update statistics or not.

Reimplemented in Ogre::D3D9RenderWindow.

◆ _updateAutoUpdatedViewports()

virtual void Ogre::RenderTarget::_updateAutoUpdatedViewports ( bool updateStatistics = true )

virtualinherited

Method for manual management of rendering - renders only viewports that are auto updated.

Remarks: This also fires preViewportUpdate and postViewportUpdate, and manages statistics. You should call it between _beginUpdate() and _endUpdate(). See _beginUpdate for more details.

Parameters

updateStatistics Whether you want to update statistics or not.

See also: _beginUpdate()

◆ _endUpdate()

virtual void Ogre::RenderTarget::_endUpdate ( )

virtualinherited

Method for manual management of rendering - finishes statistics calculation and fires 'postRenderTargetUpdate'.

Remarks: You should call it after a _beginUpdate

See also: _beginUpdate for more details.

Reimplemented in Ogre::D3D9RenderWindow.
