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

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.
border	none, fixed, resize	resize	The type of window border (in windowed mode)
outerDimensions	true, false	false	Whether the width/height is expressed as the size of the outer window, rather than the content area

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,

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:

[Main thread]Call preExtraThreadsStarted
[Main thread]Start other thread, wait
[Other thread]Call registerThread, notify main thread & continue
[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.

	)		`[virtual, inherited]`

Tell the render system whether to derive a depth bias on its own based on the values passed to it in setCurrentPassIterationCount.

The depth bias set will be baseValue + iteration * multiplier

Parameters:

derive	True to tell the RS to derive this automatically
baseValue	The base value to which the multiplier should be added
multiplier	The amount of depth bias to apply per iteration
