Detailed Description

Depth and view-space normals prepass.

Renders all opaque geometry with a minimal vertex-only shader to populate:

• A full-resolution depth buffer consumed by LightCullPass and AmbientOcclusionPass.
• A view-space normals image consumed by AmbientOcclusionPass.

Must execute before any pass that reads depth or normals.

Member Function Documentation

Execute()

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

Frustum-culls and renders all mesh submissions into the depth and normals targets.

Parameters

meshes	Static mesh submissions gathered by the scene this frame.
frustum	Camera frustum used to cull out-of-view meshes.

GetDepthImage()

Ref< Image2D > Raven::Prepass::GetDepthImage ( ) const

inline

Returns the depth image written by this pass.

Returns

Full-resolution DEPTH32F image in DepthStencilAttachment layout after Execute.

GetNormalImage()

Ref< Image2D > Raven::Prepass::GetNormalImage ( ) const

inline

Returns the view-space normals image written by this pass.

Returns

Full-resolution RGBA16F normals image after Execute.

Init()

void Raven::Prepass::Init	(	u32	width,
		u32	height,
		Ref< UniformBuffer >	cameraUBO )

Creates the depth and normals images, framebuffer, pipeline, and render pass.

Parameters

width	Render target width in pixels.
height	Render target height in pixels.
cameraUBO	Shared camera UBO providing the view-projection matrix.

Shutdown()

void Raven::Prepass::Shutdown

(

)

Releases all GPU resources owned by this pass.

UpdateInput()

template<typename... Args>

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

inline

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

Template Parameters

Args	Forwarded to RenderPass::SetInput.
