## Constructor & Destructor Documentation

Ogre::GLFrameBufferObject::GLFrameBufferObject | ( | GLFBOManager * | manager,
|  | uint | fsaa
| ) |  |

Ogre::GLFrameBufferObject::~GLFrameBufferObject | ( |  | ) |

## Member Function Documentation

void Ogre::GLFrameBufferObject::attachDepthBuffer | ( | DepthBuffer * | depthBuffer | ) |

This function acts very similar to.

See also:
  GLFBORenderTexture::attachDepthBuffer The difference between D3D & OGL is that D3D setups the DepthBuffer before rendering, while OGL setups the DepthBuffer per FBO. So the DepthBuffer (RenderBuffer) needs to be attached for OGL.

void Ogre::GLFrameBufferObject::bind | ( |  | ) |

Bind FrameBufferObject.

void Ogre::GLFrameBufferObject::bindSurface | ( | size_t | attachment,
|  | const GLSurfaceDesc & | target
| ) |  |

Bind a surface to a certain attachment point.

attachment: 0..OGRE_MAX_MULTIPLE_RENDER_TARGETS-1

void Ogre::GLFrameBufferObject::detachDepthBuffer | ( |  | ) |

PixelFormat Ogre::GLFrameBufferObject::getFormat | ( |  | ) |

GLsizei Ogre::GLFrameBufferObject::getFSAA | ( |  | ) |

GLuint Ogre::GLFrameBufferObject::getGLFBOID | ( |  | ) | const

Get the GL id for the FBO.

Definition at line 69 of file OgreGLFrameBufferObject.h.

GLuint Ogre::GLFrameBufferObject::getGLMultisampleFBOID | ( |  | ) | const

Get the GL id for the multisample FBO.

Definition at line 71 of file OgreGLFrameBufferObject.h.

size_t Ogre::GLFrameBufferObject::getHeight | ( |  | ) |

GLFBOManager* Ogre::GLFrameBufferObject::getManager | ( |  | ) |

Definition at line 79 of file OgreGLFrameBufferObject.h.

const GLSurfaceDesc& Ogre::GLFrameBufferObject::getSurface | ( | size_t | attachment | ) |

Definition at line 80 of file OgreGLFrameBufferObject.h.

size_t Ogre::GLFrameBufferObject::getWidth | ( |  | ) |

Accessors.

void Ogre::GLFrameBufferObject::initialise | ( |  | ) | `[private]`

Initialise object (find suitable depth and stencil format).

Must be called every time the bindings change. It fails with an exception (ERR_INVALIDPARAMS) if:

- Attachment point 0 has no binding
- Not all bound surfaces have the same size
- Not all bound surfaces have the same internal format

void Ogre::GLFrameBufferObject::swapBuffers | ( |  | ) |

Swap buffers - only useful when using multisample buffers.

void Ogre::GLFrameBufferObject::unbindSurface | ( | size_t | attachment | ) |

Unbind attachment.
