Member Function Documentation

void Ogre::GLESRenderSystem::_applyObliqueDepthProjection ( Matrix4 matrix,
const Plane plane,
bool  forGpuProgram 
) [virtual]

See RenderSystem.

Implements Ogre::RenderSystem.

void Ogre::GLESRenderSystem::_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::GLESRenderSystem::_convertProjectionMatrix ( const Matrix4 matrix,
Matrix4 dest,
bool  forGpuProgram = false 
) [virtual]

See RenderSystem.

Implements Ogre::RenderSystem.

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::GLESRenderSystem::_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:

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  
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

mipFilterThe filter used between mipmap levels, FO_NONE disables mipmapping
virtual void Ogre::RenderSystem::_setTextureUnitSettings ( size_t  texUnit,
TextureUnitState tl 
) [virtual, inherited]

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,

) [virtual, inherited]

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.

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.

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:

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:
enabledIf 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:
enabledIf 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.
void Ogre::GLESRenderSystem::shutdown ( void  ) [virtual]
