Member Function Documentation

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.

Viewport * Ogre::RenderTarget::addViewport (  Camera *    cam, int    ZOrder = 0, float    left = 0, float    top = 0, float    width = 100, float    height = 100 )  [virtual, inherited]

Adds a viewport to the rendering target. Remarks: A viewport is the rectangle into which redering 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 percentage, 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 percentage. top  The relative position of the top of the viewport on the target, as a percentage. width  The relative width of the viewport on the target, as a percentage. height  The relative height of the viewport on the target, as a percentage.

void Ogre::D3D8RenderWindow::create (  String    name, int    width, int    height, int    colourDepth, bool    fullScreen, int    left, int    top, bool    depthBuffer, void *    miscParam, ...    )  [virtual]

Creates & displays the new window. Parameters: width  The width of the window in pixels. height  The height of the window in pixels. colourDepth  The colour depth in bits. Ignored if fullScreen is false since the desktop depth is used. fullScreen  If true, the window fills the screen, with no title bar or border. left  The x-position of the window. Ignored if fullScreen = true. top  The y-position of the window. Ignored if fullScreen = true. depthBuffer  Specify true to include a depth-buffer. miscParam  A variable number of pointers to platform-specific arguments. The actual requirements must be defined by the implementing subclasses. Implements Ogre::RenderWindow.

void Ogre::D3D8RenderWindow::destroy (  void    )  [virtual]

Destroys the window. Implements Ogre::RenderWindow.

void Ogre::RenderTarget::firePostUpdate (  void    )  [protected, virtual, inherited]

void Ogre::D3D8RenderWindow::getCustomAttribute (  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. Parameters: name  The name of the attribute. pData  Pointer to memory of the right kind of structure to receive the info. Reimplemented from Ogre::RenderTarget.

LPDIRECT3DDEVICE8 Ogre::D3D8RenderWindow::getD3DDevice (  void    )  [inline]

void Ogre::RenderTarget::getStatistics (  float &    lastFPS, float &    avgFPS, float &    bestFPS, float &    worstFPS )  [virtual, inherited]

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 RenderSystem::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.

Viewport * Ogre::RenderTarget::getViewport (  unsigned short    index )  [virtual, inherited]

Retrieves a pointer to the viewport with the given index.

Used to retrieve or set the active state of the render target. Reimplemented in Ogre::D3D7RenderWindow.

bool Ogre::D3D8RenderWindow::isActive (    )  [inline, virtual]

Used to retrieve or set the active state of the render target. Reimplemented from Ogre::RenderTarget.

bool Ogre::D3D8RenderWindow::isClosed (    )  [inline, virtual]

Indicates whether the window has been closed by the user. Implements Ogre::RenderWindow.

bool Ogre::RenderWindow::isFullScreen (  void    )  [virtual, inherited]

Returns true if window is running in fullscreen mode.

void Ogre::D3D8RenderWindow::outputText (  int    x, int    ty, const String &    text )  [virtual]

void Ogre::D3D8RenderWindow::reposition (  int    left, int    top )  [inline, virtual]

Reposition the window. Implements Ogre::RenderWindow.

bool Ogre::D3D8RenderWindow::requiresTextureFlipping (    )  const [inline, virtual]

Implements Ogre::RenderTarget.

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

Resets saved frame-rate statistices.

void Ogre::D3D8RenderWindow::resize (  int    width, int    height )  [virtual]

Alter the size of the window. Implements Ogre::RenderWindow.

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

Used to retrieve the active state of the render target. Reimplemented in Ogre::D3D9RenderWindow.

void Ogre::RenderTarget::setDebugText (  const String &    text )  [virtual, inherited]

Adds debug text to this window.

virtual void Ogre::RenderTarget::setPriority (  uchar    priority )  [inline, 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.

void Ogre::RenderTarget::setStatsDisplay (  StatFlags    sf )  [virtual, inherited]

DEPRECATED Set what kind of statistics display (if any) should be displayed by the system about this target. Remarks: This method is now DEPRECATED. Use Root::showDebugOverlay instead. OGRE keeps details about the current rendering performance, and can display this on screen if required. This method allows you to specify what should be displayed. Alternatively, the application can retrieve the stats using RenderTarget::getStatistics and report them itself. Parameters: sf  Flags indicating which stats to display. Details are in StatFlags

void Ogre::D3D8RenderWindow::swapBuffers (  bool    waitForVSync = true )  [virtual]

Swaps the frame buffers to display the next frame. Remarks: All render windows 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). Implements Ogre::RenderWindow.

void Ogre::RenderWindow::update (  void    )  [virtual, inherited]

Updates the window contents. Remarks: The window is updated by telling each camera which is supposed to render into this window to render it's view, and then the window buffers are swapped via swapBuffers() Reimplemented from Ogre::RenderTarget.

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

void Ogre::D3D8RenderWindow::WindowMovedOrResized (  void    )  [protected]

LRESULT Ogre::D3D8RenderWindow::WndProc (  HWND    hWnd, UINT    uMsg, WPARAM    wParam, LPARAM    lParam )  [static, protected]

void Ogre::D3D8RenderWindow::writeContentsToFile (  const String &    filename )  [virtual]

Overridden - see RenderTarget. Implements Ogre::RenderTarget.
