OutputNodeRenderer *	createRenderer (RenderList &r) const noexcept override
	Create a renderer in a given context for this node.

void	startRendering () override

void	render () override

void	stopRendering () override

bool	canRender () const override

Public Member Functions inherited from score::gfx::OutputNode
virtual void	setVSyncCallback (std::function< void()>)
	Set a callback to drive rendering when there is a single output.

virtual void	updateGraphicsAPI (GraphicsApi)

GpuResourceRegistry &	acquireRegistry ()
	Persistent GPU resource registry for this output.

GpuResourceRegistry *	registry () const noexcept
	Non-owning accessor. Returns null if no registry has been acquired yet (e.g. queried before the first RenderList::init).

void	releaseRegistry ()
	Tear down the registry's QRhi resources directly. Idempotent.

Public Member Functions inherited from score::gfx::Node
	Node (const Node &)=delete

	Node (Node &&)=delete

Node &	operator= (const Node &)=delete

Node &	operator= (Node &&)=delete

virtual void	renderedNodesChanged ()
	Whenever render nodes are added / removed.

virtual void	process (Message &&msg)
	Process a message from the execution engine.

virtual void	update ()

void	materialChange () noexcept
	Used to notify a material change from the model to the renderers.

bool	hasMaterialChanged (int64_t &renderer) const noexcept

void	renderTargetChange () noexcept
	Used to notify a render target (texture inlet) change from the model to the renderers.

bool	hasRenderTargetChanged (int64_t &renderer) const noexcept

bool	hasExplicitRenderTargetSize (int32_t port) const noexcept
	Whether a given port has a user-specified render target size.

QSize	resolveRenderTargetSize (int32_t port, RenderList &renderer) const noexcept

RenderTargetSpecs	resolveRenderTargetSpecs (int32_t port, RenderList &renderer) const noexcept

void	process (int32_t port, const ossia::render_target_spec &v)
