Constructor & Destructor Documentation

GTAOPass ( const RendererConfiguration &  config,
const GBufferPass &  gBufferPass 
)

Constructs a GTAOPass.

Parameters
configThe renderer configuration.
gBufferPassReference to the G-buffer pass providing input textures.

Member Function Documentation

vireo::ImageFormat getColorAttachmentFormat ( ) const
inlineoverridevirtual

Returns the image format of the AO buffer (single R8 channel).

Reimplemented from lysa::PostProcessingCompute::getColorAttachmentFormat()

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

Renders the GTAO pass.

Parameters
commandListCommand list to record rendering commands into.
sceneScene frame data (camera matrices, etc.).
depthAttachmentDepth attachment of the current frame.
frameIndexIndex of the current frame.

Reimplemented from lysa::PostProcessingCompute::render()

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

Recreates the output image to match the new extent.

Parameters
extentNew viewport dimensions.

Reimplemented from lysa::PostProcessingCompute::resize()
