Detailed Description

Frame Buffer Object abstraction.

Constructor & Destructor Documentation

GLFrameBufferObject()

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

~GLFrameBufferObject()

Ogre::GLFrameBufferObject::~GLFrameBufferObject

Member Function Documentation

bind()

bool Ogre::GLFrameBufferObject::bind ( bool  recreateIfNeeded )

virtual

Bind FrameBufferObject.

Attempt to bind on incompatible GL context will cause FBO destruction and optional recreation.

Implements Ogre::GLFrameBufferObjectCommon.

swapBuffers()

void Ogre::GLFrameBufferObject::swapBuffers

(

)

Swap buffers - only useful when using multisample buffers.

attachDepthBuffer()

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.

detachDepthBuffer()

void Ogre::GLFrameBufferObject::detachDepthBuffer

(

)

getManager()

GLFBOManager* Ogre::GLFrameBufferObject::getManager ( )
