Member Function Documentation

void Ogre::GLES2FrameBufferObject::attachDepthBuffer

(

DepthBuffer *

depthBuffer

)

This function acts very similar to.

See also:

GLES2FBORenderTexture::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::GLES2FrameBufferObject::bind

(

)

Bind FrameBufferObject.

void Ogre::GLES2FrameBufferObject::bindSurface	(	size_t	attachment,
		const GLES2SurfaceDesc &	target
	)

Bind a surface to a certain attachment point.

void Ogre::GLES2FrameBufferObject::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

)

See AndroidResource.

(

)

See AndroidResource.

void Ogre::GLES2FrameBufferObject::swapBuffers

(

)

Swap buffers - only useful when using multisample buffers.

void Ogre::GLES2FrameBufferObject::unbindSurface

(

size_t

attachment

)

Unbind attachment.
