Manta is designed to run at the maximum frame rate possible (like a video game) it is never idle. If your application needs to do something else during the rendering loop with the cores running manta threads, perhaps that activity could be placed inside of a parallel animation callback?

It is possible to force synchronization between Manta threads and a GUI (for example) by adding a serial animation callback that waits at a barrier shared with the GUI thread. You'd need to use the synchronization primitives in Core/Thread/. It seems likely that ray tracing will be the bottleneck in most traditional graphics applications- is this not the case in your situation?

Hi,

Is there a way (condition variable?) to stop the renderer after every
frame is drawn make really idle when "idle"?
