Member Function Documentation

void score::gfx::Graph::setVSyncCallback ( std::function< void()> cb )

Set a callback to drive rendering when there is a single output.

If we render to a single window, we can use the GPU V-Sync mechanism. Otherwise the implementation will create timers to keep things in sync.
