Constructor & Destructor Documentation

TransparencyPass	(	const RendererConfiguration &	config,
		bool	withStencil
	)

Parameters

config	The renderer configuration
withStencil

auto getAccumBuffer ( const uint32 frameIndex )

inline

auto getRevealageBuffer ( const uint32 frameIndex )

inline

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

Renders the transparency pass

Parameters

commandList	The command list to record rendering commands into
scene	The scene frame data
colorAttachment	The target color attachment
depthAttachment	The target depth attachment
clearAttachment	Whether to clear the color 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).

void updatePipelines ( const std::unordered_map< pipeline_id, std::vector< unique_id >> & pipelineIds )

Updates the OIT graphics pipelines based on active pipeline IDs

Parameters

pipelineIds Map of pipeline IDs to unique object IDs
