Detailed Description

Forward+ geometry pass; the primary shading stage of the Illumine pipeline.

Renders all opaque meshes. The HDR colour output is consumed by SkyboxPass and then ToneMapPass.

All shared UBOs are injected via the Dependencies struct at Init time; their lifetimes are guaranteed by SceneRenderer to exceed this pass.

Member Function Documentation

Execute()

void Raven::GeometryPass::Execute	(	const std::vector< StaticMeshSubmission > &	meshes,
		const ShaderSettingsData &	settings,
		const Crux::Frustum &	frustum )

Frustum-culls and renders all mesh submissions with PBR shading.

Parameters

meshes	Static mesh submissions gathered by the scene this frame.
settings	Shader knobs to upload before drawing.
frustum	Camera frustum used to cull out-of-view meshes.

GetFramebuffer()

Ref< Framebuffer > Raven::GeometryPass::GetFramebuffer ( ) const

inline

Returns the HDR colour framebuffer written by this pass.

GetPass()

Ref< RenderPass > Raven::GeometryPass::GetPass ( ) const

inline

Returns the render pass object (consumed by SkyboxPass as a subpass target).

Init()

void Raven::GeometryPass::Init	(	u32	width,
		u32	height,
		const Dependencies &	deps,
		const ShaderSettingsData &	settings )

Allocates the HDR framebuffer, pipeline, and settings UBOs.

Parameters

width	Render target width in pixels.
height	Render target height in pixels.
deps	Shared GPU resource references.
settings	Initial shader settings to upload.

RecreatePass()

void Raven::GeometryPass::RecreatePass ( u32 tileX, u32 tileY, Ref< Image2D > shadowMap )

inline

Updates the tile info UBO and rebinds the shadow map after a resolution change.

Called by SceneRenderer when LightCullPass or ShadowPass signal that dependent resources need to be rebuilt.

Note

Post-v0.1 this should be generalised into a full pass recreation path.

Parameters

tileX	New tile count along X.
tileY	New tile count along Y.
shadowMap	New shadow depth map to bind.

Shutdown()

void Raven::GeometryPass::Shutdown

(

)

Releases all GPU resources owned by this pass.

UpdateInput()

template<typename... Args>

void Raven::GeometryPass::UpdateInput ( Args &&... args )

inline

Updates a named input binding and rebakes the render pass descriptor set.

Template Parameters

Args	Forwarded to RenderPass::SetInput.
