Detailed Description

OpenGL supports 3 different methods: FBO, pbuffer & Copy. Each one has it's own limitations. Non-FBO methods are solved using "dummy" DepthBuffers. That is, a DepthBuffer pointer is attached to the RenderTarget (for the sake of consistency) but it doesn't actually contain a Depth surface/renderbuffer (mDepthBuffer & mStencilBuffer are null pointers all the time) Those dummy DepthBuffers are identified thanks to their GL context. Note that FBOs don't allow sharing with the main window's depth buffer. Therefore even when FBO is enabled, a dummy DepthBuffer is still used to manage the windows.

Member Function Documentation

◆ _notifyRenderTargetAttached()

virtual void Ogre::DepthBuffer::_notifyRenderTargetAttached ( RenderTarget * renderTarget )

virtualinherited

Called when a RenderTarget is attaches this DepthBuffer.

Remarks: This function doesn't actually attach. It merely informs the DepthBuffer which RenderTarget did attach. The real attachment happens in RenderTarget::attachDepthBuffer()

Parameters

renderTarget The RenderTarget that has just been attached

◆ _notifyRenderTargetDetached()

virtual void Ogre::DepthBuffer::_notifyRenderTargetDetached ( RenderTarget * renderTarget )

virtualinherited

Called when a RenderTarget is detaches from this DepthBuffer.

Remarks: Same as DepthBuffer::_notifyRenderTargetAttached()

Parameters

renderTarget The RenderTarget that has just been detached

◆ _setPoolId()

void Ogre::DepthBuffer::_setPoolId ( uint16 poolId )

inherited

Sets the pool id in which this DepthBuffer lives.

Note this will detach any render target from this depth buffer

◆ bindToFramebuffer()

void Ogre::GL3PlusDepthBuffer::bindToFramebuffer ( GLenum target = GL_FRAMEBUFFER )

◆ copyTo()

bool Ogre::DepthBuffer::copyTo ( DepthBuffer * destination )

inherited

Copies the contents of the DepthBuffer to the destination.

Useful when you want to bind a DepthBuffer for sampling as a texture, but later resume rendering with this depth buffer (binding a DepthBuffer as a texture forces it to be decompressed and disables other optimization algorithms on a lot of Hardware. GCN Tahiti aka AMD Radeon R9 280 is no longer affected by this issue)

Remarks: The function will throw if the depth buffers are incompatible (e.g. different resolution, different format, different MSAA settings)

Parameters

destination DepthBuffer to copy to.

Returns: False if failed to copy for hardware reasons (DX10 does not allow copying MSAA depth buffer; DX10.1 does)

◆ isCompatible()

virtual bool Ogre::GL3PlusDepthBuffer::isCompatible	(	RenderTarget *	renderTarget,
		bool	exactFormatMatch
	)		const

virtual

Returns whether the specified RenderTarget is compatible with this DepthBuffer That is, this DepthBuffer can be attached to that RenderTarget.

Remarks: Most APIs impose the following restrictions: Width & height must be equal or higher than the render target's They must be of the same bit depth. They need to have the same FSAA setting

Parameters

renderTarget	The render target to test against
exactFormatMatch	True if looking for the exact format according to the RT's preferred format. False if the RT's preferred format should be ignored.

Reimplemented from Ogre::DepthBuffer.

◆ isDepthTexture()

◆ isManual()

bool Ogre::DepthBuffer::isManual ( ) const

inherited

Manual DepthBuffers are cleared in RenderSystem's destructor.

Non-manual ones are released with it's render target (aka, a backbuffer or similar)

Member Data Documentation

◆ AvailableDepthFormats

uint8 Ogre::DepthBuffer::AvailableDepthFormats

staticinherited

During initialization DefaultDepthBufferFormat is overriden with a supported format.

This can be troublesome when creating the first render window, as you cannot tell Ogre which format do you wish to use for that window.

That's where AvailableDepthFormats comes in:

Before initialization user can set this mask to inform which formats they want to use. Ogre will go from best format to worst until a supported one is found. The default value is all bits set.

Set this to 0 to never use depth buffers. If you only wish render windows to not use depth buffers, then create the window with miscParam["depth_buffer"] = "no";

After initialization the mask is left untouched

See DepthBuffer::DepthFormatsMask
