Inheritance diagram for score::gfx::DisplayVSyncClock:

Detailed Description

Wraps ScreenNode's swap-chain vsync callback path (clock #1, push).

start(tick) forwards tick straight into OutputNode::setVSyncCallback, so the compositor drives the render exactly as before; stop() clears it.

Member Function Documentation

kind()

Kind score::gfx::DisplayVSyncClock::kind ( ) const

inlineoverridevirtualnoexcept

Implements score::gfx::RenderClock.

start()

void score::gfx::DisplayVSyncClock::start ( std::function< void()>  tick )

overridevirtual

Begin delivering ticks.

tick is invoked once per render tick, on the render thread. The clock owns the tick source (timer, vsync registration, or hardware wait loop).

Implements score::gfx::RenderClock.

stop()

void score::gfx::DisplayVSyncClock::stop ( )

overridevirtual

Stop delivering ticks and release the underlying tick source.

Implements score::gfx::RenderClock.
