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  )

virtualinherited

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.

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.

minFilter	The filter used when a texture is reduced in size
magFilter	The filter used when a texture is magnified
mipFilter	The filter used between mipmap levels, FO_NONE disables mipmapping

virtual void Ogre::RenderSystem::_setTextureUnitSettings ( size_t  texUnit, TextureUnitState &  tl  )

virtualinherited

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  )

virtualinherited

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 )

virtualinherited

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.

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.

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.
