no: it's all up to you. the floating point values are passed to the GL API underneath. > > o Move Timelines to pure time-based objects. > > Will timelines now run exclusively with the default fps setting? Can I > be certain that n_frames is still time*default_fps ? there are no more frames. every time the scene is redrawn, all the timelines advance of the corresponding time elapsed since the last paint. the redraw cycle is bound to the sync-to-vblank rate or, in case your driver does not support it correctly, we have a default FPS setting that can be tweaked. ciao, Emmanuele. -- Emmanuele Bassi, Senior Engineer | emmanuele.ba...@intel.com Intel Open Source Technology Center | http://oss.intel.com -- To unsubscribe send a mail to clutter+unsubscr...@o-hand.com
