Member Function Documentation

◆ addOutputPass()

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

Implements score::gfx::NodeRenderer.

◆ initState()

void score::gfx::VideoNodeRenderer::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.

◆ release()

void score::gfx::VideoNodeRenderer::release ( RenderList &  r)
overridevirtual

Implements score::gfx::NodeRenderer.

◆ releaseState()

void score::gfx::VideoNodeRenderer::releaseState ( RenderList &  renderer)
overridevirtual

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

Reimplemented from score::gfx::NodeRenderer.

◆ removeOutputPass()

void score::gfx::VideoNodeRenderer::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.

◆ renderTargetForInput()

TextureRenderTarget score::gfx::VideoNodeRenderer::renderTargetForInput ( const Port &  input)
overridevirtual

Reimplemented from score::gfx::NodeRenderer.

◆ runRenderPass()

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

Reimplemented from score::gfx::NodeRenderer.

◆ update()

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

Implements score::gfx::NodeRenderer.
