## Member Function Documentation

void Ogre::GLRenderSystem::_applyObliqueDepthProjection | ( | Matrix4 & | matrix,
|  | const Plane & | plane,
|  | bool | forGpuProgram
| ) |  | `[virtual]`

See RenderSystem.

Implements Ogre::RenderSystem.

void Ogre::GLRenderSystem::_beginFrame | ( | void |  | ) | `[virtual]`

See RenderSystem.

Implements Ogre::RenderSystem.

virtual void Ogre::RenderSystem::_beginGeometryCount | ( | void |  | ) | `[virtual, inherited]`

The RenderSystem will keep a count of tris rendered, this resets the count.

void Ogre::RenderSystem::_cleanupDepthBuffers | ( | bool | bCleanManualBuffers = `true` | ) | `[inherited]`

Removes all depth buffers.

Should be called on device lost and shutdown

Remarks:
  Advanced users can call this directly with bCleanManualBuffers=false to remove all depth buffers created for RTTs; when they think the pool has grown too big or they've used lots of depth buffers they don't need anymore, freeing GPU RAM.

void Ogre::GLRenderSystem::_convertProjectionMatrix | ( | const Matrix4 & | matrix,
|  | Matrix4 & | dest,
|  | bool | forGpuProgram = `false`
| ) |  | `[virtual]`

See RenderSystem.

Implements Ogre::RenderSystem.

DepthBuffer* Ogre::GLRenderSystem::_createDepthBufferFor | ( | RenderTarget * | renderTarget | ) | `[virtual]`

Creates a DepthBuffer that can be attached to the specified RenderTarget.

Remarks:
  It doesn't attach anything, it just returns a pointer to a new DepthBuffer Caller is responsible for putting this buffer into the right pool, for attaching, and deleting it. Here's where API-specific magic happens. Don't call this directly unless you know what you're doing.

Implements Ogre::RenderSystem.

RenderWindow* Ogre::GLRenderSystem::_createRenderWindow | ( | const String & | name,
|  | unsigned int | width,
|  | unsigned int | height,
|  | bool | fullScreen,
|  | const NameValuePairList * | miscParams = `0`
| ) |  | `[virtual]`

Creates a new rendering window.

Remarks:
  This method creates a new rendering window as specified by the paramteters. The rendering system could be responible for only a single window (e.g. in the case of a game), or could be in charge of multiple ones (in the case of a level editor). The option to create the window as a child of another is therefore given. This method will create an appropriate subclass of RenderWindow depending on the API and platform implementation.

  After creation, this window can be retrieved using getRenderTarget().

Parameters:

  name | The name of the window. Used in other methods later like setRenderTarget and getRenderTarget.
  width | The width of the new window.
  height | The height of the new window.
  fullScreen | Specify true to make the window full screen without borders, title bar or menu bar.

  miscParams

  A NameValuePairList describing the other parameters for the new rendering window. Options are case sensitive. Unrecognised parameters will be ignored silently. These values might be platform dependent, but these are present for all platforms unless indicated otherwise:

  Key | Type/Values | Default | Description | Notes
  title | Any string | RenderTarget name | The title of the window that will appear in the title bar |
  colourDepth | 16, 32 | Desktop depth | Colour depth of the resulting rendering window; only applies if fullScreen | Win32 Specific
  left | Positive integers | Centred | Screen x coordinate from left |
  top | Positive integers | Centred | Screen y coordinate from left |
  depthBuffer | true, false | true | Use depth buffer | DirectX9 specific
  externalWindowHandle | Win32: HWND as integer GLX: poslong:posint:poslong (display*:screen:windowHandle) or poslong:posint:poslong:poslong (display*:screen:windowHandle:XVisualInfo*) OS X: WindowRef for Carbon or NSWindow for Cocoa address as an integer iOS: UIWindow address as an integer | 0 (none) | External window handle, for embedding the OGRE render in an existing window |

  externalGLControl

  true, false

  false

  Let the external window control OpenGL i.e. don't select a pixel format for the window, do not change v-sync and do not swap buffer. When set to true, the calling application is responsible of OpenGL initialization and buffer swapping. It should also create an OpenGL context for its own rendering, Ogre will create one for its use. Then the calling application must also enable Ogre OpenGL context before calling any Ogre function and restore its OpenGL context after these calls.

  OpenGL specific

  externalGLContext | Context as Unsigned Long | 0 (create own context) | Use an externally created GL context | OpenGL Specific
  parentWindowHandle | Win32: HWND as integer GLX: poslong:posint:poslong (display*:screen:windowHandle) or poslong:posint:poslong:poslong (display*:screen:windowHandle:XVisualInfo*) | 0 (none) | Parent window handle, for embedding the OGRE in a child of an external window |
  macAPI | String: "cocoa" or "carbon" | "carbon" | Specifies the type of rendering window on the Mac Platform. | Mac OS X Specific |

  macAPICocoaUseNSView

  bool "true" or "false"

  "false"

  On the Mac platform the most diffused method to embed OGRE in a custom application is to use Interface Builder and add to the interface an instance of OgreView. The pointer to this instance is then used as "externalWindowHandle". However, there are cases where you are NOT using Interface Builder and you get the Cocoa NSView* of an existing interface. For example, this is happens when you want to render into a Java/AWT interface. In short, by setting this flag to "true" the Ogre::Root::createRenderWindow interprets the "externalWindowHandle" as a NSView* instead of an OgreView*. See OgreOSXCocoaView.h/mm.

  Mac OS X Specific

  contentScalingFactor

  Positive Float greater than 1.0

  The default content scaling factor of the screen

  Specifies the CAEAGLLayer content scaling factor. Only supported on iOS 4 or greater. This can be useful to limit the resolution of the OpenGL ES backing store. For example, the iPhone 4's native resolution is 960 x 640. Windows are always 320 x 480, if you would like to limit the display to 720 x 480, specify 1.5 as the scaling factor.

  iOS Specific

  externalViewHandle | UIView pointer as an integer | 0 | External view handle, for rendering OGRE render in an existing view | iOS Specific |
  externalViewControllerHandle | UIViewController pointer as an integer | 0 | External view controller handle, for embedding OGRE in an existing view controller | iOS Specific |

  minFilter | The filter used when a texture is reduced in size
  magFilter | The filter used when a texture is magnified

virtual void Ogre::RenderSystem::_setTextureUnitSettings | ( | size_t | texUnit,
|  | TextureUnitState & | tl
| ) |  | `[virtual, inherited]`

Utility function for setting all the properties of a texture unit at once.

This method is also worth using over the individual texture unit settings because it only sets those settings which are different from the current settings for this unit, thus minimising render state changes.

virtual void Ogre::RenderSystem::_setVertexTexture | ( | size_t | unit,
|  | const TexturePtr & | tex
| ) |  | `[virtual, inherited]`

Binds a texture to a vertex sampler.

Remarks:
  Not all rendersystems support separate vertex samplers. For those that do, you can set a texture for them, separate to the regular texture samplers, using this method. For those that don't, you should use the regular texture samplers which are shared between the vertex and fragment units; calling this method will throw an exception.

virtual void Ogre::RenderSystem::addListener | ( | Listener * | l | ) | `[virtual, inherited]`

Adds a listener to the custom events that this render system can raise.

Remarks:
  Some render systems have quite specific, internally generated events that the application may wish to be notified of. Many applications don't have to worry about these events, and can just trust OGRE to handle them, but if you want to know, you can add a listener here.

  Events are raised very generically by string name. Perhaps the most common example of a render system specific event is the loss and restoration of a device in DirectX; which OGRE deals with, but you may wish to know when it happens.

void Ogre::GLRenderSystem::postExtraThreadsStarted | ( |  | ) | `[virtual]`

Implements Ogre::RenderSystem.

void Ogre::GLRenderSystem::preExtraThreadsStarted | ( |  | ) | `[virtual]`

Tell the rendersystem to perform any prep tasks it needs to directly before other threads which might access the rendering API are registered.

Remarks:
  Call this from your main thread before starting your other threads (which themselves should call registerThread()). Note that if you start your own threads, there is a specific startup sequence which must be respected and requires synchronisation between the threads:
  1. [Main thread]Call preExtraThreadsStarted
  2. [Main thread]Start other thread, wait
  3. [Other thread]Call registerThread, notify main thread & continue
  4. [Main thread]Wake up & call postExtraThreadsStarted
  Once this init sequence is completed the threads are independent but this startup sequence must be respected.

Implements Ogre::RenderSystem.

void Ogre::GLRenderSystem::processInputDevices | ( | void |  | ) | `[private]`

void Ogre::GLRenderSystem::registerThread | ( |  | ) | `[virtual]`

Register the an additional thread which may make calls to rendersystem-related objects.

Remarks:
  This method should only be called by additional threads during their initialisation. If they intend to use hardware rendering system resources they should call this method before doing anything related to the render system. Some rendering APIs require a per-thread setup and this method will sort that out. It is also necessary to call unregisterThread before the thread shuts down.

Note:
  This method takes no parameters - it must be called from the thread being registered and that context is enough.

Implements Ogre::RenderSystem.

void Ogre::RenderSystem::setWaitForVerticalBlank | ( | bool | enabled | ) | `[inherited]`

Defines whether or now fullscreen render windows wait for the vertical blank before flipping buffers.

Remarks:
  By default, all rendering windows wait for a vertical blank (when the CRT beam turns off briefly to move from the bottom right of the screen back to the top left) before flipping the screen buffers. This ensures that the image you see on the screen is steady. However it restricts the frame rate to the refresh rate of the monitor, and can slow the frame rate down. You can speed this up by not waiting for the blank, but this has the downside of introducing 'tearing' artefacts where part of the previous frame is still displayed as the buffers are switched. Speed vs quality, you choose.

Note:
  Has NO effect on windowed mode render targets. Only affects fullscreen mode.

Parameters:

  enabled | If true, the system waits for vertical blanks - quality over speed. If false it doesn't - speed over quality.

void Ogre::RenderSystem::setWBufferEnabled | ( | bool | enabled | ) | `[inherited]`

Sets whether or not W-buffers are enabled if they are available for this renderer.

Parameters:

  enabled | If true and the renderer supports them W-buffers will be used. If false W-buffers will not be used even if available. W-buffers are enabled by default for 16bit depth buffers and disabled for all other depths.
