Member Function Documentation

◆ _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.

◆ _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::GL3PlusFBOMultiRenderTarget, Ogre::GL3PlusFBORenderTexture, and Ogre::GLES2FBOMultiRenderTarget.

◆ _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.

◆ _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.

◆ _setMipmapsUpdated()

void Ogre::RenderTarget::_setMipmapsUpdated ( void )

inlineinherited

◆ _updateViewportCullPhase01()

void Ogre::RenderTarget::_updateViewportCullPhase01	(	Viewport *	viewport,
		Camera *	renderCamera,
		Camera *	cullCamera,
		const Camera *	lodCamera,
		uint8	firstRq,
		uint8	lastRq
	)

inherited

◆ _updateViewportRenderPhase02()

virtual void Ogre::RenderTarget::_updateViewportRenderPhase02	(	Viewport *	viewport,
		Camera *	camera,
		const Camera *	lodCamera,
		uint8	firstRq,
		uint8	lastRq,
		bool	updateStatistics
	)

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.

◆ 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.

◆ addViewport()

virtual Viewport* Ogre::RenderTarget::addViewport	(	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.

◆ attachDepthBuffer()

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

Returns false if couldn't attach.

Reimplemented in Ogre::D3D11DepthTextureTarget, Ogre::D3D11NullTextureTarget, Ogre::GL3PlusDepthTextureTarget, Ogre::GLES2DepthTextureTarget, Ogre::MetalNullTextureTarget, Ogre::MetalDepthTextureTarget, Ogre::GL3PlusNullTextureTarget, Ogre::GLES2NullTextureTarget, Ogre::GL3PlusFBOMultiRenderTarget, Ogre::GL3PlusFBORenderTexture, and Ogre::GLES2FBOMultiRenderTarget.

◆ copyContentsToMemory() [1/2]

virtual void Ogre::RenderTexture::copyContentsToMemory	(	const Box &	src,
		const PixelBox &	dst,
		FrameBuffer	buffer = `FB_AUTO`
	)

virtualinherited

Copies the current contents of the render target to a pixelbox.

Remarks: See suggestPixelFormat for a tip as to the best pixel format to extract into, although you can use whatever format you like and the results will be converted.

Implements Ogre::RenderTarget.

◆ copyContentsToMemory() [2/2]

OGRE_DEPRECATED 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.

◆ 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.

Referenced by Ogre::GL3PlusTexture::getGLID().

◆ isHardwareGammaEnabled()

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

◆ setDesiredDepthBufferFormat()

void Ogre::RenderTarget::setDesiredDepthBufferFormat ( PixelFormat desiredDepthBufferFormat )

inherited

Set the desired depth buffer format.

Remarks: Ogre will try to honour this request, but if it's not supported, you may get lower precision. All formats will try to fallback to PF_D24_UNORM_S8_UINT if not supported.

: Changing this setting will cause the current depth buffer to be detached unless the old and the setting are the same.

Parameters

desiredDepthBufferFormat Must be one of the following: PF_D24_UNORM_S8_UINT PF_D24_UNORM_X8 PF_D16_UNORM PF_D32_FLOAT PF_D32_FLOAT_X24_S8_UINT

◆ setPreferDepthTexture()

void Ogre::RenderTarget::setPreferDepthTexture ( bool preferDepthTexture )

inherited

Whether this RT should be attached to a depth texture, or a regular depth buffer.

Remarks: On older GPUs, preferring depth textures may result in certain depth precisions to not be available (or use integer precision instead of floating point, etc).

: Changing this setting will cause the current depth buffer to be detached unless the old and the setting are the same.

Parameters

preferDepthTexture True to use depth textures. False otherwise (default).

◆ 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.

PixelFormat Ogre::RenderTexture::suggestPixelFormat ( ) const

virtualinherited

Suggests a pixel format to use for extracting the data in this target, when calling copyContentsToMemory.

Reimplemented from Ogre::RenderTarget.

◆ swapBuffers()

virtual void Ogre::RenderTarget::swapBuffers ( void )

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.
