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
nameThe name of the window. Used in other methods later like setRenderTarget and getRenderTarget.
widthThe width of the new window.
heightThe height of the new window.
fullScreenSpecify true to make the window full screen without borders, title bar or menu bar.
miscParamsA 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  
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  
FSAA Positive integer (usually 0, 2, 4, 8, 16) 0 Full screen antialiasing factor  
FSAAHint Depends on RenderSystem and hardware. Currently supports:
"Quality": on systems that have an option to prefer higher AA quality over speed, use it
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.  
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  
useNVPerfHUD true, false false Enable the use of nVidia NVPerfHUD  
gamma true, false false Enable hardware conversion from linear colour space to gamma colour space on rendering to the window.  
enableDoubleClick true, false false Enable the window to keep track and transmit double click messages. Win32 Specific

virtual void Ogre::RenderSystem::addListener ( Listener l)

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.

Returns the vertical texel offset value required for mapping texel origins to pixel origins in this rendersystem.

Remarks
Since rendersystems sometimes disagree on the origin of a texel, mapping from texels to pixels can sometimes be problematic to implement generically. This method allows you to retrieve the offset required to map the origin of a texel to the origin of a pixel in the vertical direction.

Implements Ogre::RenderSystem.

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.
