## Member Function Documentation

virtual void Ogre::RenderTarget::_beginUpdate | ( |  | ) | `[virtual, inherited]`

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(true);

  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, Ogre::EAGLWindow, and Ogre::EAGL2Window.

virtual void Ogre::RenderTarget::_detachDepthBuffer | ( |  | ) | `[virtual, inherited]`

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::GLESFBORenderTexture, Ogre::GLES2FBORenderTexture, Ogre::GLESFBOMultiRenderTarget, Ogre::GLES2FBOMultiRenderTarget, and Ogre::GLFBOMultiRenderTarget.

virtual void Ogre::RenderTarget::_endUpdate | ( |  | ) | `[virtual, inherited]`

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.

virtual Impl* Ogre::RenderTarget::_getImpl | ( |  | ) | `[virtual, inherited]`

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.

virtual void Ogre::RenderTarget::_notifyCameraRemoved | ( | const Camera * | cam | ) | `[virtual, inherited]`

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

virtual void Ogre::RenderTarget::_updateAutoUpdatedViewports | ( | bool | updateStatistics = `true` | ) | `[virtual, inherited]`

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()

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

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.

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

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.

virtual void Ogre::RenderTarget::addListener | ( | RenderTargetListener * | listener | ) | `[virtual, inherited]`

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.

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`
| ) |  | `[virtual, inherited]`

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 ZOrders are on top of lower ones. The actual number is irrelevant, only the relative ZOrder 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 bool Ogre::RenderTarget::attachDepthBuffer | ( | DepthBuffer * | depthBuffer | ) | `[virtual, inherited]`

Reimplemented in Ogre::GLFBORenderTexture, Ogre::GLESFBORenderTexture, Ogre::GLES2FBORenderTexture, Ogre::GLESFBOMultiRenderTarget, Ogre::GLES2FBOMultiRenderTarget, and Ogre::GLFBOMultiRenderTarget.

virtual void Ogre::RenderTexture::copyContentsToMemory | ( | const PixelBox & | dst,
|  | FrameBuffer | buffer
| ) |  | `[virtual, inherited]`

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.

virtual void Ogre::RenderTarget::detachDepthBuffer | ( |  | ) | `[virtual, inherited]`

Reimplemented in Ogre::GLFBORenderTexture, Ogre::GLESFBORenderTexture, Ogre::GLES2FBORenderTexture, Ogre::GLESFBOMultiRenderTarget, Ogre::GLES2FBOMultiRenderTarget, and Ogre::GLFBOMultiRenderTarget.

virtual void Ogre::GLES2CopyingRenderTexture::getCustomAttribute | ( | const String & | name,
|  | void * | pData
| ) |  | `[virtual]`

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.

|  | float & | worstFPS
| ) |  | const`[virtual, inherited]`

virtual bool Ogre::RenderTarget::isHardwareGammaEnabled | ( |  | ) | const`[virtual, inherited]`

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.

Definition at line 386 of file OgreRenderTarget.h.

virtual bool Ogre::RenderTarget::isPrimary | ( | void |  | ) | const`[virtual, inherited]`

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.

Implements Ogre::RenderTarget.

Definition at line 56 of file OgreGLES2RenderTexture.h.

virtual void Ogre::RenderTarget::resetStatistics | ( | void |  | ) | `[virtual, inherited]`

Resets saved frame-rate statistices.

virtual void Ogre::RenderTarget::setActive | ( | bool | state | ) | `[virtual, inherited]`

Used to set the active state of the render target.

Reimplemented in Ogre::Win32Window.

virtual void Ogre::RenderTarget::setAutoUpdated | ( | bool | autoupdate | ) | `[virtual, inherited]`

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.

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

virtual void Ogre::RenderTarget::setPriority | ( | uchar | priority | ) | `[virtual, inherited]`

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.

Definition at line 312 of file OgreRenderTarget.h.

PixelFormat Ogre::RenderTexture::suggestPixelFormat | ( |  | ) | const`[virtual, inherited]`

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

Reimplemented from Ogre::RenderTarget.

virtual void Ogre::RenderTarget::swapBuffers | ( | bool | waitForVSync = `true` | ) | `[virtual, inherited]`

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.

Parameters:

  waitForVSync

  If true, the system waits for the next vertical blank period (when the CRT beam turns off as it travels from bottom-right to top-left at the end of the pass) before flipping. If false, flipping occurs no matter what the beam position. Waiting for a vertical blank can be slower (and limits the framerate to the monitor refresh rate) but results in a steadier image with no 'tearing' (a flicker resulting from flipping buffers when the beam is in the progress of drawing the last frame).

virtual void Ogre::RenderTarget::update | ( | bool | swapBuffers = `true` | ) | `[virtual, inherited]`

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, Ogre::D3D11RenderWindow, and Ogre::D3D9MultiRenderTarget.

virtual void Ogre::RenderTarget::updateImpl | ( |  | ) | `[protected, virtual, inherited]`

Internal implementation of update()

void Ogre::RenderTarget::updateStats | ( | void |  | ) | `[protected, inherited]`

void Ogre::RenderTarget::writeContentsToFile | ( | const String & | filename | ) | `[inherited]`

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

virtual String Ogre::RenderTarget::writeContentsToTimestampedFile | ( | const String & | filenamePrefix,
|  | const String & | filenameSuffix
| ) |  | `[virtual, inherited]`

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

Returns:
  the name of the file used.
