Constructor & Destructor Documentation

SSAOPass	(	const RendererConfiguration &	config,
		const GBufferPass &	gBufferPass,
		bool	withStencil
	)

Constructs an SSAOPass

Parameters

config	The renderer configuration
gBufferPass	Reference to the G-buffer pass providing input textures
withStencil	Whether to enable stencil testing

auto getColorAttachment ( const uint32 frameIndex ) const

inline

Gets the SSAO color buffer for a specific frame

Parameters

frameIndex Index of the current frame

auto getColorAttachmentFormat ( ) const

inline

Gets the image format used for the SSAO buffer

void render	(	vireo::CommandList &	commandList,
		const SceneFrameData &	scene,
		const std::shared_ptr< vireo::RenderTarget > &	depthAttachment,
		uint32	frameIndex
	)

Renders the SSAO pass

Parameters

commandList	The command list to record rendering commands into
scene	The scene frame data
depthAttachment	The target depth attachment
frameIndex	Index of the current frame

void resize	(	const vireo::Extent &	extent,
		const std::shared_ptr< vireo::CommandList > &	commandList
	)

overridevirtual

Recreate pass resources after a resize (default: no-op).
