ForwardRenderer Class Reference

Detailed Description

Forward rendering path.

Renders opaque geometry directly to the color/depth attachments using a single forward pass, then handles transparency and optional bloom. Suitable for scenes with many materials requiring complex shading (PBR, alpha test, etc.) without a G-Buffer.

Implements lysa::Renderer::getBrightnessAttachment()

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

Recreates attachments/pipelines after a render target resize.

Parameters
extentNew swap chain extent.
commandListCommand list used for any required transitions/copies.

Reimplemented from lysa::Renderer::resize()

void update ( uint32  frameIndex)
overrideprotectedvirtual

Performs per-frame housekeeping (e.g., pass-local data updates).

Reimplemented from lysa::Renderer::update()

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

Updates graphics pipelines according to the provided materials mapping.

Parameters
pipelineIdsMap of pipeline family id to materials.
