Constructor & Destructor Documentation

FrameScalingPass ( const RendererConfiguration &  config,
const vireo::ImageFormat  outputFormat 
)
inline

Constructs the pass and selects the upscaling algorithm from the renderer configuration.

Parameters
configRenderer configuration (includes FrameScalingType and render resolution).
outputFormatPixel format of the output surface.

Member Function Documentation

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

Recomputes FSR constants when the output extent changes.

Parameters
extentNew output resolution in pixels.
