◆ setDepthBufferPool()

void Ogre::RenderTarget::setDepthBufferPool ( uint16 poolId )

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

inherited

◆ getDepthBuffer()

DepthBuffer* Ogre::RenderTarget::getDepthBuffer ( ) const

inherited

◆ attachDepthBuffer()

virtual bool Ogre::RenderTarget::attachDepthBuffer ( DepthBuffer * depthBuffer )

virtualinherited

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

◆ detachDepthBuffer()

virtualinherited

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

◆ _detachDepthBuffer()

virtual void Ogre::RenderTarget::_detachDepthBuffer ( )

virtualinherited

Detaches DepthBuffer without notifying it from the detach.

Useful when called from the DepthBuffer while it iterates through attached RenderTargets (

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.

◆ swapBuffers()

virtual void Ogre::RenderTarget::swapBuffers ( )

inlinevirtualinherited

Swaps the frame buffers to display the next frame.

Remarks: For targets that are double-buffered so that no 'in-progress' versions of the scene are displayed during rendering. Once rendering has completed (to an off-screen version of the window) the buffers are swapped to display the new frame.

Reimplemented in Ogre::D3D9RenderTexture, Ogre::D3D11RenderWindowSwapChainBased, Ogre::NaClWindow, Ogre::D3D9RenderWindow, Ogre::GLFBORenderTexture, Ogre::GL3PlusFBORenderTexture, and Ogre::GLES2FBORenderTexture.

◆ 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.

virtualinherited

Retrieves a pointer to the viewport with the given Z-order.

Remarks: throws if not found.

◆ hasViewportWithZOrder()

virtual bool Ogre::RenderTarget::hasViewportWithZOrder ( int ZOrder )

virtualinherited

Returns true if and only if a viewport exists at the given Z-order.

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]

virtual void Ogre::RenderTarget::getStatistics	(	float &	lastFPS,
		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.

Deprecated:: use getStatistics()

◆ getStatistics() [2/2]

◆ getCustomAttribute()

virtual void Ogre::RenderTarget::getCustomAttribute	(	const String &	name,
		void *	pData
	)

virtualinherited

Gets a custom (maybe platform-specific) attribute.

Remarks: This is a nasty way of satisfying any API's need to see platform-specific details. It horrid, but D3D needs this kind of info. At least it's abstracted.

Parameters

name	The name of the attribute.
pData	Pointer to memory of the right kind of structure to receive the info.

Reimplemented in Ogre::D3D9RenderTexture, Ogre::D3D11RenderTexture, Ogre::D3D9RenderWindow, Ogre::D3D11RenderWindowBase, Ogre::NaClWindow, Ogre::GLFBORenderTexture, Ogre::D3D9MultiRenderTarget, Ogre::GL3PlusFBORenderTexture, Ogre::GLES2FBORenderTexture, Ogre::GL3PlusFBOMultiRenderTarget, Ogre::GLES2FBOMultiRenderTarget, Ogre::GLCopyingRenderTexture, Ogre::GLPBRenderTexture, Ogre::D3D11MultiRenderTarget, and Ogre::GLFBOMultiRenderTarget.

◆ 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

same as addListener, but force the position in the vector, so we can control the call order

◆ removeListener()

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

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.

◆ isActive()

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

virtualinherited

Used to retrieve or set the active state of the render target.

Reimplemented in Ogre::RenderWindow, and Ogre::D3D9RenderWindow.

◆ 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.

◆ copyContentsToMemory() [2/2]

void Ogre::RenderTarget::copyContentsToMemory	(	const PixelBox &	dst,
		FrameBuffer	buffer = `FB_AUTO`
	)

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.

References Ogre::RenderTarget::copyContentsToMemory().

Referenced by Ogre::RenderTarget::copyContentsToMemory().

◆ 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.

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.

◆ isPrimary()

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

virtualinherited

Indicates whether this target 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 in Ogre::RenderWindow.

◆ 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

◆ setFSAA()

virtual void Ogre::RenderTarget::setFSAA	(	uint	fsaa,
		const String &	fsaaHint
	)

inlinevirtualinherited

Set the level of multisample AA to be used if hardware support it.

This option will be ignored if the hardware does not support it or setting can not be changed on the fly on per-target level.

Parameters

fsaa	The number of samples
fsaaHint	Any hinting text (

See also: Root::createRenderWindow)

Reimplemented in Ogre::D3D11RenderWindowSwapChainBased, and Ogre::D3D11RenderWindowBase.

◆ _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.
