Member Function Documentation

auto getAlbedoBuffer ( const uint32  frameIndex) const
inline

Gets the albedo buffer for a specific frame

Parameters
frameIndexIndex of the current frame
Returns
A shared pointer to the albedo render target
auto getEmissiveBuffer ( const uint32  frameIndex) const
inline

Gets the emissive buffer for a specific frame

Parameters
frameIndexIndex of the current frame
Returns
A shared pointer to the emissive render target
auto getNormalBuffer ( const uint32  frameIndex) const
inline

Gets the normal buffer for a specific frame

Parameters
frameIndexIndex of the current frame
Returns
A shared pointer to the normal render target
auto getPositionBuffer ( const uint32  frameIndex) const
inline

Gets the position buffer for a specific frame

Parameters
frameIndexIndex of the current frame
Returns
A shared pointer to the position render target
auto getVelocityBuffer ( const uint32  frameIndex) const
inline

Gets the velocity buffer for a specific frame

Parameters
frameIndexIndex of the current frame
Returns
A shared pointer to the velocity render target
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 G-buffer pass

Parameters
commandListThe command list to record rendering commands into
sceneThe scene frame data
colorAttachmentThe target color attachment
depthAttachmentThe target depth attachment
clearAttachmentWhether to clear the color attachment
frameIndexIndex 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).

Reimplemented from lysa::Renderpass::resize()

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

Updates the graphics pipelines based on active pipeline IDs

Parameters
pipelineIdsMap of pipeline IDs to unique object IDs
