Application running

Is possible implementing a OF project that run as a service/daemon/background, or console mode ?

In GUI mode is possible draw some things only one more time or only when i needed to draw ?

Hi, look in the examples/windowing/noWindowExample.
if you want to draw only when needed probably the best way is to draw into an ofFbo and update it when needed. Take a look into the fbo examples.
best

Thanks
