Member Function Documentation

◆ addOutputPass()

void score::gfx::GenericNodeRenderer::addOutputPass	(	RenderList &	renderer,
		Edge &	edge,
		QRhiResourceUpdateBatch &	res
	)

overridevirtual

Create a pass for a new output edge (pipeline, SRB, processUBO).

Reimplemented from score::gfx::NodeRenderer.

◆ hasOutputPassForEdge()

bool score::gfx::GenericNodeRenderer::hasOutputPassForEdge ( Edge & edge ) const

overridevirtual

Check if this renderer already has an output pass for the given edge.

Reimplemented from score::gfx::NodeRenderer.

◆ init()

void score::gfx::GenericNodeRenderer::init	(	RenderList &	renderer,
		QRhiResourceUpdateBatch &	res
	)

overridevirtual

Implements score::gfx::NodeRenderer.

◆ initState()

void score::gfx::GenericNodeRenderer::initState	(	RenderList &	renderer,
		QRhiResourceUpdateBatch &	res
	)

overridevirtual

Initialize edge-independent state: material UBO, samplers, mesh, shaders. Called once when the renderer enters a RenderList.

Reimplemented from score::gfx::NodeRenderer.

Reimplemented in score::gfx::TexgenNode::Rendered.

◆ release()

void score::gfx::GenericNodeRenderer::release ( RenderList & r )

overridevirtual

Implements score::gfx::NodeRenderer.

◆ releaseState()

void score::gfx::GenericNodeRenderer::releaseState ( RenderList & renderer )

overridevirtual

Release edge-independent state. Called once when the renderer leaves a RenderList.

Reimplemented from score::gfx::NodeRenderer.

Reimplemented in score::gfx::TexgenNode::Rendered.

◆ removeOutputPass()

void score::gfx::GenericNodeRenderer::removeOutputPass	(	RenderList &	renderer,
		Edge &	edge
	)

overridevirtual

Remove the pass for a removed output edge. Pure-virtual: every concrete renderer must explicitly handle edge removal. Sinks (OutputNodeRenderer) and data-only renderers that store no per-edge GPU state can override with an empty body.

Implements score::gfx::NodeRenderer.

◆ runRenderPass()

void score::gfx::GenericNodeRenderer::runRenderPass	(	RenderList &	renderer,
		QRhiCommandBuffer &	commands,
		Edge &	edge
	)

overridevirtual

Reimplemented from score::gfx::NodeRenderer.

◆ update()

void score::gfx::GenericNodeRenderer::update	(	RenderList &	renderer,
		QRhiResourceUpdateBatch &	res,
		Edge *	edge
	)

overridevirtual

Implements score::gfx::NodeRenderer.

◆ updateInputTexture()

void score::gfx::GenericNodeRenderer::updateInputTexture	(	const Port &	input,
		QRhiTexture *	tex,
		QRhiTexture *	depthTex = `nullptr`
	)

overridevirtual

Updates the sampler texture for an input port. Called when the upstream texture may have changed (edge add, RT recreation). If the port has SamplableDepth and depthTex is non-null, the depth sampler (immediately after the color sampler) is also updated.

Reimplemented from score::gfx::NodeRenderer.
