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 Cocoa: OgreGLView address as an integer. You can pass NSView or NSWindow too, but should perform OgreGLView callbacks into the Ogre manually. 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 |
  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 |
  externalSharegroup | EAGLSharegroup pointer as an integer | 0 | External sharegroup, used to shared GL resources between contexts | iOS Specific |
  Full Screen | true, false | false | Specify whether to create the window in full screen mode | OS X Specific |
  MSAA | Positive integer (usually 1, 2, 4, 8, 16) | 1 | Multisample antialiasing factor |
  MSAA_Quality | Depends on RenderSystem and hardware. Currently supports: 0 ... infinite number (depends on HW) | Blank | Full screen antialiasing hint |
  displayFrequency | Refresh rate in Hertz (e.g. 60, 75, 100) | Desktop vsync rate | Display frequency rate, for fullscreen mode |
  vsync | true, false | false | Synchronize buffer swaps to monitor vsync, eliminating tearing at the expense of a fixed frame rate |
  vsyncInterval | 1, 2, 3, 4 | 1 | If vsync is enabled, the minimum number of vertical blanks that should occur between renders. For example if vsync is enabled, the refresh rate is 60 and this is set to 2, then the frame rate will be locked at 30. |

## ◆ preExtraThreadsStarted()

void Ogre::GLES2RenderSystem::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.

## ◆ registerThread()

void Ogre::GLES2RenderSystem::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.
