> Is the "ground cache" for the benefit of the FDM? The FDMs are currently the only users of the groundcache, and yes, they benefit from it. A lot. Per-wheel/contact-point ground awareness hadn't been done before Mathias implemented the ground cache. And probably it would have been a big performance problem to constantly do intersection test with the whole tile. Still, I didn't mean to blame the problems on the FDMs. I just called it "FDM stuttering" because this is what the user sees (and because the ground-cache code is in the FDM/ directory :-) But the FDM only stuttered, because it wasn't called in time, because of unfortunate groundcache/beacon interaction. And that wasn't really a bug, either. Neither in the beacon, nor in the ground cache. Just a detail that had to be tuned for better performance. :-) m. _______________________________________________ Flightgear-devel mailing list [email protected] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
