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 camera,
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
viewportThe viewport you want to update, it must be bound to the rendertarget.
updateStatisticsWhether 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
camThe camera from which the viewport contents will be rendered (mandatory)
ZOrderThe 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)
leftThe relative position of the left of the viewport on the target, as a value between 0 and 1.
topThe relative position of the top of the viewport on the target, as a value between 0 and 1.
widthThe relative width of the viewport on the target, as a value between 0 and 1.
heightThe relative height of the viewport on the target, as a value between 0 and 1.

virtual

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.

◆ 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.

deactivatea value of 'true' will cause the window to deactivate itself when it loses focus. 'false' will allow it to continue to render even when window focus is lost.
Note
'true' is the default behavior.

◆ setDepthBufferPool()

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

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

Reimplemented in Ogre::D3D11DepthTextureTarget, Ogre::GL3PlusDepthTextureTarget, Ogre::GLES2DepthTextureTarget, and Ogre::MetalDepthTextureTarget.

◆ 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
desiredDepthBufferFormatMust 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

◆ 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
fsaaThe number of samples
fsaaHintAny hinting text (

Root::createRenderWindow)

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

◆ setFsaaResolved()

◆ setFsaaResolveDirty()

◆ setFullscreen()

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

Alter fullscreen mode options.

Note
Nothing will happen unless the settings here are different from the current settings.
Parameters
fullScreenWhether to use fullscreen mode or not.
widthThe new width to use
heightThe new height to use

Reimplemented from Ogre::RenderWindow.

◆ 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, Ogre::GLXWindow, Ogre::CocoaWindow, and Ogre::Win32Window.

◆ 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
preferDepthTextureTrue 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.

◆ setVisible()

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

Set the visibility state.

Reimplemented in Ogre::GLXWindow, and Ogre::EGLWindow.

◆ setVSyncEnabled()

virtual void Ogre::RenderWindow::setVSyncEnabled ( bool  vsync)
inlinevirtualinherited

◆ setVSyncInterval()

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

Set the vertical sync interval.

This indicates the number of vertical retraces to wait for before swapping buffers. A value of 1 is the default.

Reimplemented in Ogre::D3D9RenderWindow, Ogre::GLXWindow, and Ogre::Win32Window.

◆ suggestPixelFormat()

PixelFormat Ogre::RenderWindow::suggestPixelFormat ( ) const
inlinevirtualinherited

Override since windows don't usually have alpha.

Reimplemented from Ogre::RenderTarget.

References Ogre::PF_BYTE_RGB.

◆ swapBuffers()

void Ogre::GTKWindow::swapBuffers ( void  )
virtual

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 from Ogre::RenderTarget.

◆ windowMovedOrResized()

virtual void Ogre::RenderWindow::windowMovedOrResized ( void  )
inlinevirtualinherited

Notify that the window has been resized.

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

Reimplemented in Ogre::D3D9RenderWindow, Ogre::GLXWindow, Ogre::CocoaWindow, Ogre::Win32Window, and Ogre::MetalRenderWindow.

◆ writeContentsToFile()

void Ogre::RenderTarget::writeContentsToFile ( const String filename,
PixelFormat  format = PF_UNKNOWN 
)
inherited

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

If format is unspecified (PF_UNKNOWN), the most suitable one is automatically chosen.

◆ writeContentsToTimestampedFile()

virtual String Ogre::RenderTarget::writeContentsToTimestampedFile ( const String filenamePrefix,
const String filenameSuffix,
PixelFormat  format = PF_UNKNOWN 
)
virtualinherited

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

Returns
the name of the file used.
