Member Function Documentation

void Ogre::GL3PlusFrameBufferObject::attachDepthBuffer

(

DepthBuffer *

depthBuffer

)

This function acts very similar to.

See also

GL3PlusFBORenderTexture::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::GL3PlusFrameBufferObject::bind

(

)

Bind FrameBufferObject.

void Ogre::GL3PlusFrameBufferObject::bindSurface	(	size_t	attachment,
		const GL3PlusSurfaceDesc &	target
	)

Bind a surface to a certain attachment point.

Accessors.

void Ogre::GL3PlusFrameBufferObject::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::GL3PlusFrameBufferObject::swapBuffers

(

)

Swap buffers - only useful when using multisample buffers.

void Ogre::GL3PlusFrameBufferObject::unbindSurface

(

size_t

attachment

)

Unbind attachment.
