Detailed Description

Renders the environment cubemap as a background skybox.

Draws a unit cube with a reverse-depth trick so that the skybox only fills pixels not covered by opaque geometry. Renders into the same Framebuffer as GeometryPass using the shared depth attachment, so it must execute after geometry but before ToneMapPass.

Member Function Documentation

Execute()

void Raven::SkyboxPass::Execute

(

)

Renders the skybox cube into the shared HDR framebuffer.

GetPipeline()

Ref< Pipeline > Raven::SkyboxPass::GetPipeline ( )

inline

Returns the skybox pipeline.

GetRenderPass()

Ref< RenderPass > Raven::SkyboxPass::GetRenderPass ( )

inline

Returns the render pass used by this pass.

GetVertexBuffer()

Ref< VertexBuffer > Raven::SkyboxPass::GetVertexBuffer ( )

inline

Returns the unit cube vertex buffer.

Init()

void Raven::SkyboxPass::Init	(	Ref< Framebuffer >	framebuffer,
		Ref< Image2D >	depthImage,
		Ref< TextureCube >	activeCubemap,
		Ref< UniformBuffer >	cameraUBO )

Initialises the skybox pipeline, render pass, and cube vertex buffer.

Parameters

framebuffer	Shared HDR framebuffer from GeometryPass.
depthImage	Shared depth image from Prepass (used to reject foreground pixels).
activeCubemap	Initial environment cubemap to sample.
cameraUBO	Shared camera UBO providing the view-projection matrix.

Shutdown()

void Raven::SkyboxPass::Shutdown

(

)

Releases all GPU resources owned by this pass.

UpdateInput()

template<typename... Args>

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

inline

Rebinds a named input (e.g. the active cubemap) and rebakes the descriptor set.

Called by SceneRenderer when the active cubemap changes.

Template Parameters

Args	Forwarded to RenderPass::SetInput.
