## Member Function Documentation

virtual void Ogre::GLPBRTTManager::bind | ( | RenderTarget * | target | ) | `[virtual]`

Bind a certain render target.

Implements Ogre::GLRTTManager.

virtual bool Ogre::GLPBRTTManager::checkFormat | ( | PixelFormat | format | ) | `[virtual]`

Check if a certain format is usable as rendertexture format.

Implements Ogre::GLRTTManager.

virtual MultiRenderTarget* Ogre::GLRTTManager::createMultiRenderTarget | ( | const String & | name | ) | `[virtual, inherited]`

Create a multi render target.

Reimplemented in Ogre::GLFBOManager.

virtual RenderTexture* Ogre::GLPBRTTManager::createRenderTexture | ( | const String & | name,
|  | const GLSurfaceDesc & | target,
|  | bool | writeGamma,
|  | uint | fsaa
| ) |  | `[virtual]`

Create a texture rendertarget object.

Implements Ogre::GLRTTManager.

virtual void Ogre::GLRTTManager::getBestDepthStencil | ( | GLenum | internalFormat,
|  | GLenum * | depthFormat,
|  | GLenum * | stencilFormat
| ) |  | `[virtual, inherited]`

Reimplemented in Ogre::GLFBOManager.

Definition at line 87 of file OgreGLRenderTexture.h.

References GL_NONE.

GLContext* Ogre::GLPBRTTManager::getContextFor | ( | PixelComponentType | ctype,
|  | size_t | width,
|  | size_t | height
| ) |  |

Get GL rendering context for a certain component type and size.

static GLRTTManager & Ogre::Singleton< GLRTTManager >::getSingleton | ( | void |  | ) | `[static, inherited]`

Definition at line 90 of file OgreSingleton.h.

static GLRTTManager * Ogre::Singleton< GLRTTManager >::getSingletonPtr | ( | void |  | ) | `[static, inherited]`

Definition at line 92 of file OgreSingleton.h.

virtual PixelFormat Ogre::GLRTTManager::getSupportedAlternative | ( | PixelFormat | format | ) | `[virtual, inherited]`

Get the closest supported alternative format.

If format is supported, returns format.

void Ogre::GLPBRTTManager::releasePBuffer | ( | PixelComponentType | ctype | ) |

Release PBuffer for a certain pixel format.

void Ogre::GLPBRTTManager::requestPBuffer | ( | PixelComponentType | ctype,
|  | size_t | width,
|  | size_t | height
| ) |  |

Create PBuffer for a certain pixel format and size.

virtual void Ogre::GLPBRTTManager::unbind | ( | RenderTarget * | target | ) | `[virtual]`

Unbind a certain render target.

This is called before binding another RenderTarget, and before the context is switched. It can be used to do a copy, or just be a noop if direct binding is used.

Implements Ogre::GLRTTManager.
