Constructor & Destructor Documentation

ShadowMapPass	(	const Light *	light,
		const DeviceMemoryArray &	meshInstancesDataArray,
		size_t	maxMeshSurfacePerPipeline
	)

Constructs a ShadowMapPass

Parameters

light	Pointer to the light source for which shadows are generated
meshInstancesDataArray	Array of mesh instance data in device memory
maxMeshSurfacePerPipeline	Maximum number of mesh surfaces per pipeline

Member Function Documentation

void compute	(	vireo::CommandList &	commandList,
		const std::unordered_map< uint32, std::unique_ptr< GraphicPipelineData >> &	pipelinesData
	)		const

Computes frustum culling for shadow map generation

Parameters

commandList	The command list to record compute commands into
pipelinesData	Map of pipeline data for mesh rendering

auto getCascadeSplitDepth ( const uint32 index ) const

inline

Gets the cascade split depth for a shadow map

Parameters

index Index of the shadow map

Returns: The split depth

const auto& getLightSpace ( const uint32 index ) const

inline

Gets the light space matrix for a shadow map

Parameters

index Index of the shadow map

Returns: The light space matrix

auto getShadowMap ( const uint32 index ) const

inline

Gets a shadow map render target

Parameters

index Index of the shadow map

Returns: A shared pointer to the shadow map render target

auto getShadowMapCount ( ) const

inline

Gets the number of shadow maps (subpasses)

Returns: The number of shadow maps

auto getTransparencyColorMap ( const uint32 index ) const

inline

Gets a transparency color map render target

Parameters

index Index of the shadow map

Returns: A shared pointer to the transparency color map render target

void render	(	vireo::CommandList &	commandList,
		const SceneFrameData &	scene
	)

Renders the shadow maps

Parameters

commandList	The command list to record rendering commands into
scene	The scene frame data

void setCurrentCamera ( const Camera & camera )

inline

Sets the current camera for cascaded shadow maps calculation

Parameters

camera Reference to the current camera

void update ( uint32 frameIndex )

overridevirtual

Update any per-frame state (default: no-op).

Reimplemented from lysa::Renderpass::update()

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

Updates the graphics pipelines based on active pipeline IDs

Parameters

pipelineIds Map of pipeline IDs to unique object IDs
