RenderWindow * createRenderWindow (const String &name, unsigned int width, unsigned int height, bool fullScreen, const NameValuePairList *miscParams=0)

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 getRenderWindow.
	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 platorms unless indicated otherwise:

Key: "title" Description: The title of the window that will appear in the title bar Values: string Default: RenderTarget name

Key: "colourDepth" Description: Colour depth of the resulting rendering window; only applies if fullScreen is set. Values: 16 or 32 Default: desktop depth Notes: [W32 specific]

Key: "displayFrequency" Description: Display frequency rate, for fullscreen mode Values: 60...? Default: Desktop vsync rate

Key: "vsync" Description: Synchronize buffer swaps to vsync Values: true, false Default: 0

Key: "border" Description: The type of window border (in windowed mode) Values: none, fixed, resize Default: resize

Key: "outerDimensions" Description: Whether the width/height is expressed as the size of the outer window, rather than the content area Values: true, false Default: false

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.

RenderSystem::getRenderSystemEvents

virtual void Ogre::RenderSystem::attachRenderTarget ( RenderTarget & target ) [virtual, inherited]

Attaches the passed render target to the render system.

colour The colour to clear the colour buffer with, if enabled

depth The value to initialise the depth buffer with, if enabled

stencil The value to initialise the stencil buffer with, if enabled.

Implements Ogre::RenderSystem.

virtual void Ogre::RenderSystem::convertColourValue ( const ColourValue & colour,

uint32 * pDest

) [virtual, inherited]

Generates a packed data version of the passed in ColourValue suitable for use as with this RenderSystem.

Remarks:
Since different render systems have different colour data formats (eg RGBA for GL, ARGB for D3D) this method allows you to use 1 method for all.

Parameters:

colour The colour to convert

HardwareOcclusionQuery* Ogre::GLRenderSystem::createHardwareOcclusionQuery ( void ) [virtual]

Create an object for performing hardware occlusion queries.

Implements Ogre::RenderSystem.

virtual MultiRenderTarget* Ogre::GLRenderSystem::createMultiRenderTarget ( const String & name ) [virtual]

Surfaces can be bound and unbound at will. This fails if mCapabilities->numMultiRenderTargets() is smaller than 2.

Implements Ogre::RenderSystem.

RenderTexture* Ogre::RenderSystem::createRenderTexture ( const String & name,

unsigned int width,

unsigned int height,

TextureType texType = TEX_TYPE_2D,

PixelFormat internalFormat = PF_X8R8G8B8,

const NameValuePairList * miscParams = 0

) [inherited]

Creates and registers a render texture object.

Parameters:

name The name for the new render texture. Note that names must be unique.

width The requested width for the render texture. See Remarks for more info.

height The requested width for the render texture. See Remarks for more info.

texType The type of texture; defaults to TEX_TYPE_2D

internalFormat The internal format of the texture; defaults to PF_X8R8G8B8

miscParams This parameter is ignored.

Returns:
On succes, a pointer to a new platform-dependernt, RenderTexture-derived class is returned. On failiure, NULL is returned.

Remarks:
Because a render texture is basically a wrapper around a texture object, the width and height parameters of this method just hint the preferred size for the texture. Depending on the hardware driver or the underlying API, these values might change when the texture is created. The same applies to the internalFormat parameter.

Deprecated:
This method is deprecated, and exists only for backward compatibility.
You can create arbitrary rendertextures with the TextureManager::createManual call with usage TU_RENDERTARGET.
Reimplemented in Ogre::D3D9RenderSystem.

RenderWindow* Ogre::GLRenderSystem::createRenderWindow ( const String & name,

unsigned int width,

unsigned int height,

bool fullScreen,

const NameValuePairList * miscParams = 0

) [virtual]

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 getRenderWindow.

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 platorms unless indicated otherwise:

Key: "title" Description: The title of the window that will appear in the title bar Values: string Default: RenderTarget name

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 avalible 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 avalible. W-buffers are enabled by default for 16bit depth buffers and disabled for all other depths.
