Naively I would do it just before each frame, using the time delta since the last update, but apparently you've got something other in mind. > Is there a construct like glutTimerFunc?

Afaik glutTimerFunc is still called in between frames (GLUT is single-threaded), so one could simply check if enough time has elapsed at each frame to get the same functionality in Eq. We *could* call a timer function asynchronously, but you wouldn't be able to do anything useful there since your render threads are accessing the data. I think the most sane place is still between frameFinish and frameStart, unless your animation update is expensive. I guess if you're not happy with doing animations on a per-frame base, I would need more background requirements to understand what you need.
